Figure 7. Schematic Diagram of a 4 W TOPSwitch-II Standby Power Supply using an 8 lead PDIP.  
Application Examples  
the full universal AC input range. The TOP221 is packaged in  
an 8 pin power DIP package.  
Following are just two of the many possible TOPSwitch  
implementations. Refer to the Data Book and Design Guide  
for additional examples.  
The output voltage (5 V) is directly sensed by the Zener  
diode (VR1) and the optocoupler (U2). The output voltage is  
determined by the sum of the Zener voltage and the volt-  
age drop across the LED of the optocoupler (the voltage  
drop across R1 is negligible). The output transistor of the  
optocoupler drives the CONTROL pin of the TOP221. C5  
bypasses the CONTROL pin and provides control loop com-  
pensation and sets the auto-restart frequency.  
4 W Standby Supply using 8 Lead PDIP  
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.  
The transformer’s leakage inductance voltage spikes are  
snubbed by R3 and C1 through diode D1. The bias winding  
is rectified and filtered by D3 and C4 providing a non-isolat-  
ed 12 V output which is also used to bias the collector of the  
optocoupler’s output transistor. The isolated 5 V output wind-  
ing is rectified by D2 and filtered by C2, L1 and C3.  
For this application the input rectifiers and input filter are  
sized for the main supply and are not shown. The input DC  
rail may vary from 100 V to 380 V DC which corresponds to
