XC9141/XC9142 Series  
ETR04018-002  
Load Disconnection Function, 0.8A Step-up DC/DC Converters  
GreenOperation-compatible  
GENERAL DESCRIPTION  
XC9141/XC9142 series are synchronous step-up DC/DC converters with a 0.3(TYP.) N-channel driver transistor and a  
0.3(TYP.) synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 0.8A  
by reducing ON resistance of the built-in transistors.  
The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a  
100load resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery.  
The output voltage can be set from 1.8V to 5.5V (±2.0%) in steps of 0.1V.With the built-in oscillator, either 1.2MHz or 3.0MHz can  
be selected for suiting to your particular application.  
During the devices enter stand-by mode, A, D types prevent the application malfunction by CL Discharge Function which can  
quickly discharge the electric charge at the output capacitor (CL). B, E types is able to drive RTC etc. by Bypass Switch Function  
to maintain continuity between the input and output. C, F types is able to connect in parallel with other power supplies by Load  
Disconnection Function which breaks continuity between the input and output.

Select components appropriate to the usage conditions (ambient temperature, input & output voltage).  
While selecting a part, please concern about capacitance reduction and voltage durability.  
In the case of fosc=1.2MHz: If VOUT(T)3.5V and the load current rises above 200mA, use two or more in a parallel connection.  
In the case of fosc=3.0MHz: If VBAT2V, VOUT(T)3.5V and the load current rises above 200mA, use two or more in a parallel connection.  
For the actual load capacitance, use a ceramic capacitor that ensures a capacitance equivalent to or greater than the GRM188R60J106ME84  
(Murata).  
If using tantalum or low ESR electrolytic capacitors please be aware that ripple voltage will be higher due to the larger ESR (Equivalent Series  
Resistance) values of those types of capacitors. Please also note that the IC’s operation may become unstable with such capacitors so that  
we recommend to test on the board before usage.  
If using electrolytic capacitor for the CL, please connect a ceramic capacitor in parallel.

BLOCK DIAGRAM  
The error amplifier compares the internal reference voltage with the resistors RFB1 and RFB2. Phase compensation is performed on the  
resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time of the N-channel driver transistor during  
PWM operation. The PWM comparator compares, in terms of voltage level, the signal from the error amplifier with the ramp wave from the ramp  
wave circuit, and delivers the resulting output to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is  
continuously performed to ensure stable output voltage. The current feedback circuit monitors the N-channel driver transistor’s turn-on current  
for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback  
loop even when a low ESR capacitor, such as a ceramic capacitor, is used, ensuring stable output voltage.  
<Reference voltage source, soft start function>  
The reference voltage forms a reference that is used to stabilize the output voltage of the IC.  
After “H” level is fed to CE pin, the reference voltage connected to the error amp increases linearly during the soft start interval. This allows the  
voltage divided by the internal RFB1 and RFB2 resistors and the reference voltage to be controlled in a balanced manner, and the output voltage  
rises in proportion to the rise in the reference voltage. This operation prevents rush input current and enables the output voltage to rise smoothly.  
<Ramp Wave Circuit>  
The ramp wave circuit determines switching frequency. The frequency is fixed internally at 1.2MHz/3.0MHz. The Clock generated is  
used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits.  
<Error Amplifier>  
The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the feedback voltage divided by  
the internal resistors (RFB1 and RFB2). When the FB is lower than the reference voltage, output voltage of the error amplifier increases. The  
gain and frequency characteristics of the error amplifier are optimized internally.  
<VDDMAX  
>
V
DD MAX circuit compares the input voltage and the output voltage then it will select the higher one as the power supply for the IC.  
<Shutdown function, load disconnection function>  
The IC enters chip disable state by applying low level voltage to the CE pin. At this time, the N-channel and P-channel synchronous switching  
transistors are turned OFF. With XC9142C type, the load disconnection function activates even during shutdown, and because the input voltage  
VBAT and output voltage VOUT are compared to optimally control the orientation of the parasitic diode of the P-channel synchronous switching  
transistor, a parallel connection with other power supplies is possible. With the XC9141 series and XC9142A/B types, the orientation of the  
parasitic diode of the P-channel synchronous switching transistor is fixed at anode: VOUT and cathode: Lx during shutdown to break conduction  
from the input side to the output side by the parasitic diode of the P-channel synchronous switching transistor.  
<PWM/PFM control circuit>  
When PFM operates, the N-channel driver transistor turns on at the timing of the signal sent from the PWM comparator. The N-channel driver  
transistor remains on until the current in the coil reaches a constant current (IPFM). The PWM/PFM control circuit compares the signal sent from  
the PWM comparator to the time it takes the current in the coil to reach a constant current (IPFM), and outputs the pulse that results in a longer on-  
time of the N-channel driver transistor. This enables smooth switching between PWM and PFM. The XC9141 series directly outputs the signal  
that is sent from the PWM comparator.

OPERATIONAL EXPLANATION (Continued)  
<Maximum current limit function, short-circuit protection>  
The maximum current limit function of XC9141A/B types and XC9142A/B/C types constantly monitors the current flowing in the N-channel driver  
transistor connected to the Lx pin, and if the current in the N-channel driver transistor exceeds the current limit, the function turns off the N-channel  
driver transistor. (Please refer to Fig. ILIM①)  
If the current flowing in the N-channel driver transistor exceeds the current limit value (equivalent to the peak coil current), the N-channel  
driver transistor turns off, and remains off during the clock interval.  
At the next clock, the N-channel driver transistor turns on.  
If overcurrent continues, and are repeated.  
Note that the current in the internal N-channel driver transistor is not the same as the output current IOUT

The maximum current limit function of XC9141D/E and XC9142D/E/F types monitors the current that flows in the N-channel driver transistor  
connected to the Lx pin, and consists of both maximum current limiting and a latch function. (Please refer to Fig.ILIM)  
Short-circuit protection is a latch-stop function that activates when the output voltage drops below the short-circuit protection threshold voltage in  
the overcurrent state. (Please refer to Fig.ILIM)  
If the current flowing in the N-channel driver transistor exceeds the current limit value (equivalent to the peak coil current), the N-channel  
driver transistor turns off, and remains off during the clock interval. In addition, an integral latch timer starts the count.  
The N-channel driver transistor turns on at the next pulse. If in the overcurrent state at this time, the N-channel driver transistor turns off as  
in (1). The integral latch timer continues the count.  
If the count of the integral latch timer continues for 300μs typ.(@fosc=1.2MHz), a function that latches the N-channel driver transistor and P-  
channel synchronous switching transistor to the off state activates.  
If no longer in the overcurrent state at the next pulse, normal operation resumes. The integral latch timer stops the count.  
If the output voltage VOUT drops below the shrt-circuprotectiothhold voltge VSHORT during the count of the integral latch timer, a  
function that latches the N-channel driver transistor and P-channl sychronous switching transistor in the off state activates. The short-  
circuit protection threshold voltage VSHORT is a threshold voltage that is linked to the input voltage VBAT  
.
In the latched state, either restart by shutting down once with the CE pin, or resume operation by lowering the input voltage VBAT below the  
latch release voltage VLAT_R(1.2V typ.). The soft start function operates during restart. During the soft-start interval tSS, the integral latch timer  
and latch function are stopped.  
When the input voltage VBAT is below the latch release voltage VLAT_R(1.2V typ.), the integral latch timer and latch function stop, but the current  
limiting function continues operating.

XC9141/XC9142 Series  
OPERATIONAL EXPLANATION (Continued)  
<CL Discharge>  
The XC9141A/D type and XC9142A/D type can discharge the electric charge at the output capacitor (CL) when a low signal to the CE pin which  
enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin and the GND pin. When the IC  
is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it may avoid application malfunction. Discharge time of the  
output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge  
resistance value [RDCHG] and an output capacitor value (CL) as τ(τ= CL x RDCHG), discharge time of the output voltage after discharge via the N  
channel transistor is calculated by the following formulas. However, the CL discharge resistance [RDCHG] is depends on the VBAT or VOUT. We  
recommend that you fully check actual performance.  
V = VOUT x e -t / τ or t = τ x ln (VOUT / V)

<Bypass switch>  
At shutdown, XC9141B/E type and XC9142B/E type conduct between the BAT pin and VOUT pin by means of a bypass switch. If the output is  
shorted to ground, the current is limited by the resistance (RBSW) of the bypass switch.

Series  
NOTE ON USE  
1)  
For the phenomenon of temporal and transitional voltage decrease or voltage increase, the IC may be damaged or deteriorated if IC is used  
beyond the absolute maximum ratings.  
2)  
Spike noise and ripple voltage arise in a switching regulator as with a DC/DC converter. These are greatly influenced by external component  
selection, such as the coil inductance, capacitance values, and board layout of external components. Once the design has been completed,  
verification with actual components should be done.  
3)  
The DC/DC converter performance is greatly influenced by not only the ICs' characteristics, but also by those of the external components.  
Care must be taken when selecting the external components. Especially for CL load capacitor, it is recommended to use type B capacitors  
(JIS regulation) or X7R, X5R capacitors (EIA regulation).  
4)  
5)  
6)  
7)  
Use a ground wire of sufficient strength. Ground potential fluctuation caused by the ground current during switching could cause the IC  
operation to become unstable, so reinforce the area around the GND pin of the IC in particular.  
Please mount each external component as close to the IC as possible. Also, please make traces thick and short to reduce the circuit  
impedance.  
With regard to the current limiting value (ILIM), the actual coil current may at times exceed the electrical characteristics due to propagation  
delay inside the product.  
The CE pin is a CMOS input pin. Do not use with the pin open. If connecting to the BAT pin or ground pin, use the resistor which is 1Mor  
less. To prevent malfunctioning of the device connected to this product or the input/output due to short circuiting between pins, it is  
recommended that a resistor be connected.  
8)  
9)  
In case of connecting to another power supply as shown in below circuit diagram, please use the XC9142C/F type. Connecting another  
external power supply to the output of any other type may destroy the IC.  
The maximum current limiter controls the limit of the N-channel driver transistor by monitoring current flow. This function does not limit the  
current flow of the P-channel synchronous transistor. When used with the condition VBAT > VOUT (input voltage higher than the output voltage),  
the IC may be destroyed if overcurrent flows to the P-channel synchronous switching transistor due to short-circuiting of the load or other  
reason.  
10) When the device is used in high step-up ratio, the current limit function may not work during excessive load current. In this case, the  
maximum duty cycle limits maximum current. In this event, latching may not take place on XC9141D/E types and XC9142D/E/F types (“latch  
types” below) because the maximum current limit cannot be detected.  
11) On latch types, some board conditions may cause release from the maximum current limit, and the integrated latch time may become longer  
or latching may not take place.  
12) If the status heavy load and large output capacitor is connected or the input voltage is low, the output voltage may overshoot, on XC9141A/B  
types and XC9142A/B/C types(“non-latch types” below). On a latch type, the maximum current limit may be detected, and this will cause  
the latch function to activate and stop operation after the soft start time elapses. In particular, note that the soft start time becomes shorter  
when the IC is used at high temperatures.  
13) When the step-up voltage difference is small, the XC9141 series for PWM control may oscillate intermittently.  
14) When the voltage boost difference is small, the current limiting function may not operate if the on time of the N-channel driver transistor is  
shorter than the propagation delay time of the current limit circuit. In this case, latching may not take place on a latch type because the  
maximum current limit is not detected.  
15) When an XC9142C/F type is used with VBAT > VOUT(T) (input voltage higher than the set output voltage), the P-channel synchronous switching  
transistor turns off but current flows to the parasitic diode. This causes excessive heat generation in the IC. Test using the actual equipment  
and note the power dissipation and heat dissipation of the package. During voltage boosting with a voltage drop due to VF of the parasitic  
diode, the output voltage may become unstable. On the XC9141 series and XC9142A/B/D/E types, the P-channel synchronous switching  
transistor turns on and the output voltage becomes equal to the input voltage. In environments where VBAT > VOUTT, the XC9141 series and  
XC9142A/B/D/E types are recommended.  
16) When input voltage and output voltage are low, integral latch function and short-circuit protection may not operate.  
We recommend that you fully check actual performance.  
17) TOREX places an importance on improving our products and its reliability. However, by any possibility, we would request user fail-safe  
design and post-aging treatment on system or equipment.

NOTE ON USE (Continued)  
Instructions for pattern layouts  
1.  
In order to stabilize VBAT voltage level, we recommend that a by-pass capacitor CIN is connected as close as possible to the BAT and  
GND pins.  
2.  
3.  
4.  
Please mount each external component as close to the IC as possible.  
Place external components as close to the IC as possible and use thick and short traces to reduce the circuit impedance.  
Make sure that the PCB GND traces are thick and wide as possible. GND voltage level fluctuation created by high ground current at  
the time of switching may cause instability of the IC.  
5.  
The internal driver transistors bring on heat because of the IIN current and ON resistance of the driver transistors.

Note on mounting (WLP-6-01)  
6-1. Mount pad design should be optimized for user's conditions.  
6-2. Sn-AG-Cu is used for the package terminals. If eutectic solder is used, mounting reliability is decreased. Please do not  
use eutectic solder paste.  
6-3. When underfill agent is used to increase interfacial bonding strength, please take enough evaluation for selection. Some  
underfill materials and applied conditions may decrease bonding reliability.  
6-4. The IC has exposed surface of silicon material in the top marking face and sides so that it is weak against mechanical  
damages. Please take care of handling to avoid cracks and breaks.  
6-5. The IC has exposed surface of silicon material in the top marking face and sides. Please use the IC with keeping the circuit  
open (avoiding short-circuit from the out).  
6-6. Semi-transparent resin is coated on the circuit face of the package. Please be noted that the usage under strong lights may  
affects device performance.
