Standard temperature range for all parts is industrial (-40° to +85°C).  
Features  
General Description  
The Supertex HV9110 through HV9113 are a series of BiCMOS/  
DMOS single-output, pulse width modulator ICs intended for use  
in high-speed high-efficiency switchmode power supplies. They  
provide all the functions necessary to implement a single-switch  
current-mode PWM, in any topology, with a minimum of external  
parts.  
10 to 120V input range  
Current-mode control  
High efficiency  
Up to 1.0MHz internal oscillator  
Internal start-up circuit  
Low internal noise  
BecausetheyutilizeSupertex’sproprietaryBiCMOS/DMOStech-  
nology, they require less than one tenth of the operating power of  
conventional bipolar PWM ICs, and can operate at more than  
twice their switching frequency. Dynamic range for regulation is  
also increased, to approximately 8 times that of similar bipolar  
parts. They start directly from any DC input voltages between 10  
and 120VDC, requiring no external power resistor. The output  
stage is push-pull CMOS and thus requires no clamping diodes  
for protection, even when significant lead length exists between  
the output and the external MOSFET. The clock frequency is set  
with a single external resistor.  
Applications  
DC/DC converters  
Distributed power systems  
ISDN equipment  
PBX systems  
Accessory functions are included to permit fast remote shutdown  
(latching or nonlatching) and undervoltage shutdown.  
Modems  
For similar ICs intended to operate directly from up to 450VDC  
input, please consult the data sheet for the HV9120/9123.

Detailed Description  
Preregulator  
the 50% maximum duty cycle versions, a frequency dividing flip-  
flop. A single external resistor between the OSC In and OSC Out  
pins is required to set oscillator frequency (see graph). For the  
50% maximum duty cycle versions the Discharge pin is internally  
connected to GND. For the 99% duty cycle version, the discharge  
pin can either be connected to VSS directly or connected to VSS  
through a resistor used to set a deadtime.  
Thepreregulator/startupcircuitfortheHV911Xconsistsofahigh-  
voltage n-channel depletion-mode DMOS transistor driven by an  
error amplifier to form a variable current path between the VIN  
terminal and the VDD terminal. Maximum current (about 20 mA)  
occurswhenVDD =0, withcurrentreducingasVDD rises. Thispath  
shuts off altogether when VDD rises to somewhere between 7.8  
and 9.4V, so that if VDD is held at 10 or 12V by an external source  
(generallythesupplythechipiscontrolling). Nocurrentotherthan  
leakage is drawn through the high voltage transistor. This mini-  
mizes dissipation.  
One difference exists between the Supertex HV911X and com-  
petitive 911Xs: On the Supertex part the oscillator is shut off  
when a shutoff command is received. This saves about 150µA of  
quiescent current, which aids in the construction of power sup-  
plies to meet CCITT specification I-430, and in other situations  
where an absolute minimum of quiescent power dissipation is  
required.  
An external capacitor between VDD and VSS is generally required  
to store energy used by the chip in the time between shutoff of the  
high voltage path and the VDD supplys output rising enough to  
take over powering the chip. This capacitor should have a value  
of 100X or more the effective gate capacitance of the MOSFET  
being driven, i.e.,  
Reference  
Cstorage 100 x (gate charge of FET at 10V ÷ 10V)  
as well as very good high frequency characteristics. Stacked  
polyester or ceramic caps work well. Electrolytic capacitors are  
generally not suitable.  
The Reference of the HV911X consists of a stable bandgap  
reference followed by a buffer amplifier which scales the voltage  
up to approximately 4.0V. The scaling resistors of the reference  
bufferamplifieraretrimmedduringmanufacturesothattheoutput  
of the error amplifier when connected in a gain of 1 configuration  
is as close to 4.000V as possible. This nulls out any input offset  
of the error amplifier. As a consequence, even though the ob-  
served reference voltage of a specific part may not be exactly  
4.0V, the feedback voltage required for proper regulation will be.  
A common resistor divider string is used to monitor VDD for both  
the undervoltage lockout circuit and the shutoff circuit of the high  
voltage FET. Setting the undervoltage sense point about 0.6V  
lower on the string than the FET shutoff point guarantees that the  
undervoltage lockout always releases before the FET shuts off.  
A 50Kresistor is placed internally between the output of the  
reference buffer amplifier and the circuitry it feeds (reference  
output pin and non-inverting input to the error amplifier). This  
allows overriding the internal reference with a low-impedance  
voltage source 6.0V. Using an external reference reinstates the  
input offset voltage of the error amplifier, and its effect of the exact  
value of feedback voltage required.  
Bias Circuit  
Anexternalbiasresistor, connectedbetweenthebiaspinandVSS  
is required by the HV911X to set currents in a series of current  
mirrors used by the analog sections of the chip. Nominal external  
bias current requirement is 15 to 20µA, which can be set by a  
390Kto 510Kresistor if a 10V VDD is used, or a 510kto  
680Kresistor if VDD will be 12V. A precision resistor is not  
required; 5% is fine.  
Becausethereferenceofthe911Xisahighimpedancenode, and  
usually there will be significant electrical noise near it, a bypass  
capacitor between the reference pin and VSS is strongly recom-  
mended. The reference buffer amplifier is intentionally compen-  
sated to be stable with a capacitive load of 0.01 to 0.1µF.  
Clock Oscillator  
The clock oscillator of the HV911X consists of a ring of CMOS  
inverters, timing capacitors, a capacitor discharge FET, and, in

Detailed Description (continued)  
Error Amplifier  
Remote Shutdown  
The error amplifier in the HV911X is a true low-power differential  
inputoperationalamplifierintendedforaround-the-amplifiercom-  
pensation. It is of mixed CMOS-bipolar construction: A PMOS  
input stage is used so the common-mode range includes ground  
and the input impedance is very high. This is followed by bipolar  
gain stages which provide high gain without the electrical noise of  
all-MOS amplifiers. The amplifier is unity-gain stable.  
The shutdown and reset pins of the 911X can be used to perform  
either latching or non-latching shutdown of a converter as re-  
quired. These pins have internal current source pull-ups so they  
can be driven from open-drain logic. When not used they should  
be left open, or connected to VDD  
.
Output Buffer  
The output buffer of the HV911X is of standard CMOS construc-  
tion (P-channel pull-up, N-channel pull-down). Thus the body-  
drain diodes of the output stage can be used for spike clipping if  
necessary, and external Schottky diode clamping of the output is  
not required.  
Current Sense Comparators  
The HV911X uses a true dual comparator system with indepen-  
dent comparators for modulation and current limiting. This allows  
thedesignergreaterlatitudeincompensationdesign,asthereare  
noclamps(exceptESDprotection)onthecompensationpin. Like  
the error amplifier, the comparators are of low-noise BiCMOS  
construction.
