Description  
Figure 1. Typical Flyback Application.  
The second generation TOPSwitch-II family is more cost  
effective and provides several enhancements over the first  
generationTOPSwitchfamily. TheTOPSwitch-IIfamilyextends  
the power range from 100W to 150W for 100/115/230 VAC  
input and from 50W to 90W for 85-265 VAC universal input.  
This brings TOPSwitch technology advantages to many new  
applications, i.e. TV, Monitor, Audio amplifiers, etc. Many  
significant circuit enhancements that reduce the sensitivity to  
board layout and line transients now make the design even  
easier. The standard 8L PDIP package option reduces cost in  
lower power, high efficiency applications. The internal lead  
frame of this package uses six of its pins to transfer heat from  
the chip directly to the board, eliminating the cost of a heat sink.  
TOPSwitch incorporates all functions necessary for a switched  
modecontrolsystemintoathreeterminalmonolithicIC:power  
MOSFET, PWM controller, high voltage start up circuit, loop  
compensation and fault protection circuitry.

TOP221-227  
TOPSwitch-II Family Functional Description (cont.)  
Control Voltage Supply  
Oscillator  
CONTROL pin voltage VC is the supply or bias voltage for the  
controller and driver circuitry. An external bypass capacitor  
closely connected between the CONTROL and SOURCE pins  
is required to supply the gate drive current. The total amount  
of capacitance connected to this pin (CT) also sets the auto-  
restart timing as well as control loop compensation. VC is  
regulated in either of two modes of operation. Hysteretic  
regulation is used for initial start-up and overload operation.  
Shunt regulation is used to separate the duty cycle error signal  
from the control circuit supply current. During start-up,  
CONTROLpin currentissuppliedfromahigh-voltageswitched  
current source connected internally between the DRAIN and  
CONTROLpins. Thecurrentsourceprovidessufficientcurrent  
to supply the control circuitry as well as charge the total  
external capacitance (CT).  
The internal oscillator linearly charges and discharges the  
internal capacitance between two voltage levels to create a  
sawtoothwaveformforthepulsewidthmodulator. Theoscillator  
setsthepulsewidthmodulator/currentlimitlatchatthebeginning  
of each cycle. The nominal frequency of 100 kHz was chosen  
to minimize EMI and maximize efficiency in power supply  
applications. Trimming of the current reference improves the  
frequency accuracy.  
Pulse Width Modulator  
The pulse width modulator implements a voltage-mode control  
loop by driving the output MOSFET with a duty cycle inversely  
proportional to the current into the CONTROL pin which  
generates a voltage error signal across RE. The error signal  
across RE is filtered by an RC network with a typical corner  
frequency of 7 kHz to reduce the effect of switching noise. The  
filtered error signal is compared with the internal oscillator  
sawtooth waveform to generate the duty cycle waveform. As  
the control current increases, the duty cycle decreases. A clock  
signal from the oscillator sets a latch which turns on the output  
MOSFET. The pulse width modulator resets the latch, turning  
off the output MOSFET. The maximum duty cycle is set by the  
symmetry of the internal oscillator. The modulator has a  
minimum ON-time to keep the current consumption of the  
TOPSwitchindependentoftheerrorsignal. Notethataminimum  
current must be driven into the CONTROL pin before the duty  
cycle begins to change.  
The first time VC reaches the upper threshold, the high-voltage  
current source is turned off and the PWM modulator and output  
transistorareactivated,asshowninFigure5(a). Duringnormal  
operation (when the output voltage is regulated) feedback  
control current supplies the VC supply current. The shunt  
regulator keeps VC at typically 5.7 V by shunting CONTROL  
pin feedback current exceeding the required DC supply current  
through the PWM error signal sense resistor RE. The low  
dynamic impedance of this pin (ZC) sets the gain of the error  
amplifier when used in a primary feedback configuration. The  
dynamic impedance of the CONTROL pin together with the  
externalresistanceandcapacitancedeterminesthecontrolloop  
compensation of the power system.  
Gate Driver  
The gate driver is designed to turn the output MOSFET on at a  
controlledratetominimizecommon-modeEMI. Thegatedrive  
current is trimmed for improved accuracy.  
If the CONTROL pin total external capacitance (CT) should  
discharge to the lower threshold, the output MOSFET is turned  
off and the control circuit is placed in a low-current standby  
mode. Thehigh-voltagecurrentsourceturnsonandchargesthe  
external capacitance again. Charging current is shown with a  
negative polarity and discharging current is shown with a  
positive polarity in Figure 6. The hysteretic auto-restart  
comparator keeps VC within a window of typically 4.7 to 5.7 V  
by turning the high-voltage current source on and off as shown  
in Figure 5(b). The auto-restart circuit has a divide-by-8  
counter which prevents the output MOSFET from turning on  
again until eight discharge-charge cycles have elapsed. The  
counter effectively limits TOPSwitch power dissipation by  
reducing the auto-restart duty cycle to typically 5%. Auto-  
restart continues to cycle until output voltage regulation is  
again achieved.  
Error Amplifier  
The shunt regulator can also perform the function of an error  
amplifierinprimaryfeedbackapplications. Theshuntregulator  
voltageisaccuratelyderivedfromthetemperaturecompensated  
bandgap reference. The gain of the error amplifier is set by the  
CONTROL pin dynamic impedance. The CONTROL pin  
clamps external circuit signals to the VC voltage level. The  
CONTROL pin current in excess of the supply current is  
separated by the shunt regulator and flows through RE as a  
voltage error signal.  
Cycle-By-Cycle Current Limit  
The cycle by cycle peak drain current limit circuit uses the  
output MOSFET ON-resistance as a sense resistor. A current  
limitcomparatorcomparestheoutputMOSFETON-statedrain-  
source voltage, VDS(ON) with a threshold voltage. High drain  
current causes VDS(ON) to exceed the threshold voltage and turns  
the output MOSFET off until the start of the next clock cycle.  
The current limit comparator threshold voltage is temperature  
Bandgap Reference  
All critical TOPSwitch internal voltages are derived from a  
temperature-compensated bandgap reference. This reference  
is also used to generate a temperature-compensated current  
sourcewhichistrimmedtoaccuratelysettheoscillatorfrequency  
and MOSFET gate drive current.

Overtemperature Protection  
The leading edge blanking circuit inhibits the current limit  
comparator for a short time after the output MOSFET is turned  
on. The leading edge blanking time has been set so that current  
spikescausedbyprimary-sidecapacitancesandsecondary-side  
rectifier reverse recovery time will not cause premature  
termination of the switching pulse.  
Temperature protection is provided by a precision analog  
circuit that turns the output MOSFET off when the junction  
temperature exceeds the thermal shutdown temperature  
(typically 135 °C). Activating the power-up reset circuit by  
removingandrestoringinputpowerormomentarilypullingthe  
CONTROL pin below the power-up reset threshold resets the  
latch and allows TOPSwitch to resume normal power supply  
operation. VC is regulated in hysteretic mode and a 4.7 V to

pin when the power supply is latched off.  
Thecurrentlimitcanbelowerforashortperiodaftertheleading  
edge blanking time as shown in Figure 12. This is due to  
dynamic characteristics of the MOSFET. To avoid triggering  
thecurrentlimitinnormaloperation,thedraincurrentwaveform  
should stay within the envelope shown.  
High-voltage Bias Current Source  
ThiscurrentsourcebiasesTOPSwitchfromtheDRAINpinand  
charges the CONTROL pin external capacitance (CT) during  
start-up or hysteretic operation. Hysteretic operation occurs  
during auto-restart and overtemperature latched shutdown.  
The current source is switched on and off with an effective duty  
cycle of approximately 35%. This duty cycle is determined by  
the ratio of CONTROL pin charge (IC) and discharge currents  
(ICD1 and ICD2). This current source is turned off during normal  
operation when the output MOSFET is switching.  
Shutdown/Auto-restart  
To minimize TOPSwitch power dissipation, the shutdown/  
auto-restart circuit turns the power supply on and off at an auto-  
restart duty cycle of typically 5% if an out of regulation  
condition persists. Loss of regulation interrupts the external  
current into the CONTROL pin. VC regulation changes from  
shuntmodetothehystereticauto-restartmodedescribedabove.

Figure 7 shows a 4 W standby supply. This supply is used in  
appliances where certain standby functions (e.g. real time  
clock, remote control port) must be kept active even while the  
main power supply is turned off.  
The 5 V secondary is used to supply the standby function and  
the 12 V non-isolated output is used to supply power for the  
PWM controller of the main power supply and other primary  
side functions.

R2 and VR2 provide a slight pre-load on the 12 V output to  
improve load regulation at light loads. The bias winding is  
rectified and filtered by D3 and C4 to create a TOPSwitch bias

Key Application Considerations  
Short interruptions of AC power may cause TOPSwitch to  
enter the 8-count auto-restart cycle before starting again.  
This is because the input energy storage capacitors are not  
completelydischargedandtheCONTROLpincapacitance  
has not discharged below the internal power-up reset  
voltage.  
General Guidelines  
Keep the SOURCE pin length very short. Use a Kelvin  
connection to the SOURCE pin for the CONTROL pin  
bypass capacitor. Use single point grounding techniques at  
the SOURCE pin as shown in Figure 9.  
In some cases, minimum loading may be necessary to keep  
a lightly loaded or unloaded output voltage within the  
desired range due to the minimum ON-time.  
Minimize peak voltage and ringing on the DRAIN voltage  
at turn-off. Use a Zener or TVS Zener diode to clamp the  
drain voltage below the breakdown voltage rating of  
TOPSwitch under all conditions, including start-up and  
overload. The maximum recommended clamp Zener  
voltage for the TOP2XX series is 200 V and the  
corresponding maximum reflected output voltage on the  
primary is 135 V. Please see Step 4: AN-16 in the 1996-97  
Data Book and Design Guide or on our Web site.  
ReplacingTOPSwitch with TOPSwitch-II  
There is no external latching shutdown function in  
TOPSwitch-II. Otherwise, the functionality of the  
TOPSwitch-II devices is same as that of the TOPSwitch family.  
However, before considering TOPSwitch-II as a 'drop in'  
replacement in an existing TOPSwitch design, the design  
should be verified as described below.  
The transformer should be designed such that the rate of  
change of drain current due to transformer saturation is  
within the absolute maximum specification (ID in 100 ns  
before turn off as shown in Figure 13). As a guideline, for  
most common transformer cores, this can be achieved by  
maintaining the Peak Flux Density (at maximum ILIMIT  
current) below 4200 Gauss (420 mT). The transformer  
spreadsheets Rev. 2.1 (or later) for continuous and Rev.1.0  
(or later) for discontinuous conduction mode provide the  
necessary information.  
The new TOPSwitch-II family offers more power capability  
than the original TOPSwitch family for the same MOSFET  
RDS(ON). Therefore, the original TOPSwitch design must be  
reviewed to make sure that the selected TOPSwitch-II  
replacement device and other primary components are not over  
stressed under abnormal conditions.  
The following verification steps are recommended:  
Do not plug TOPSwitch into a hotIC socket during test.  
External CONTROL pin capacitance may be charged to  
excessive voltage and cause TOPSwitch damage.  
Checkthetransformerdesigntomakesurethatitmeetsthe  
ID specification as outlined in the General Guidelines  
section above.  
While performing TOPSwitch device tests, do not exceed  
maximum CONTROL pin voltage of 9 V or maximum  
CONTROL pin current of 100 mA.  
Thermal: Higher power capability of the TOPSwitch-II  
would in many instances allow use of a smaller MOSFET  
device (higher RDS(ON)) for reduced cost. This may affect  
TOPSwitchpowerdissipationandpowersupplyefficiency.  
Therefore thermal performance of the power supply must  
be verified with the selected TOPSwitch-II device.  
Under some conditions, externally provided bias or supply  
current driven into the CONTROL pin can hold the  
TOPSwitch in one of the 8 auto-restart cycles indefinitely  
and prevent starting. To avoid this problem when doing  
bench evaluations, it is recommended that the VC power  
supply be turned on before the DRAIN voltage is applied.  
TOPSwitch can also be reset by shorting the CONTROL  
pin to the SOURCE pin momentarily.  
Clamp Voltage: Reflected and Clamp voltages should be  
verified not to exceed recommended maximums for the  
TOP2XX Series: 135 V Reflected/200 V Clamp. Please  
see Step 4: AN-16 in the Data Book and Design Guide and  
readme.txt file attached to the transformer design  
spreadsheets.  
CONTROL pin currents during auto-restart operation are  
much lower at low input voltages (< 36 V) which increases  
the auto-restart cycle time (see the IC vs. DRAIN Voltage  
Characteristic curve).

NOTES:  
A. For specifications with negative values, a negative temperature coefficient corresponds to an increase in  
magnitude with increasing temperature, and a positive temperature coefficient corresponds to a decrease in  
magnitude with increasing temperature.  
B. The breakdown voltage and leakage current measurements can be accomplished as shown in Figure 15 by using  
the following sequence:  
i. The curve tracer should initially be set at 0 V. The base output should be adjusted through a voltage sequence  
of 0 V, 6.5 V, 4.3 V, and 6.5 V, as shown. The base current from the curve tracer should not exceed 100 mA. This  
CONTROL pin sequence interrupts the Auto-restart sequence and locks the TOPSwitch internal MOSFET in the  
OFF State.  
ii. The breakdown and the leakage measurements can now be taken with the curve tracer. The maximum  
voltage from the curve tracer must be limited to 700 V under all conditions.  
C. It is possible to start up and operate TOPSwitch at DRAIN voltages well below 36 V. However, the CONTROL pin  
charging current is reduced, which affects start-up time, auto-restart frequency, and auto-restart duty cycle. Refer  
to the characteristic graph on CONTROL pin charge current (IC) vs. DRAIN voltage for low voltage operation  
characteristics.

BENCH TEST PRECAUTIONS FOR EVALUATION OF ELECTRICAL CHARACTERISTICS  
The following precautions should be followed when testing  
TOPSwitch by itself outside of a power supply. The schematic  
shown in Figure 14 is suggested for laboratory testing of  
TOPSwitch.  
Auto-restartmode, thereisonlya12.5%chancethatthecontrol  
pin oscillation will be in the correct state (DRAIN active state)  
so that the continuous DRAIN voltage waveform may be  
observed. It is recommended that the VC power supply be  
turnedonfirstandtheDRAINpowersupplysecondifcontinuous  
drainvoltagewaveformsaretobeobserved. The12.5%chance  
ofbeinginthecorrectstateisduetothe8:1counter. Temporarily  
shorting the CONTROL pin to the SOURCE pin will reset  
TOPSwitch, which then will come up in the correct state.  
When the DRAIN supply is turned on, the part will be in the  
Auto-restart mode. The CONTROL pin voltage will be  
oscillating at a low frequency from 4.7 to 5.7 V and the DRAIN
