SG3526  
Pulse Width Modulation  
Control Circuit  
The SG3526 is a high performance pulse width modulator  
integrated circuit intended for fixed frequency switching regulators  
and other power control applications.  
Functions included in this IC are a temperature compensated  
voltage reference, sawtooth oscillator, error amplifier, pulse width  
modulator, pulse metering and steering logic, and two high current  
totem pole outputs ideally suited for driving the capacitance of power  
FETs at high speeds.

Additional protective features include soft start and undervoltage  
lockout, digital current limiting, double pulse inhibit, adjustable dead  
time and a data latch for single pulse metering. All digital control ports  
are TTL and Bseries CMOS compatible. Active low logic design  
allows easy wiredOR connections for maximum flexibility. The  
versatility of this device enables implementation in singleended or  
pushpull switching regulators that are transformerless or transformer  
coupled. The SG3526 is specified over a junction temperature range of  
0° to +125°C.
