SG3525A  
Pulse Width Modulator  
Control Circuit  
The SG3525A pulse width modulator control circuit offers  
improved performance and lower external parts count when  
implemented for controlling all types of switching power supplies.  
The on−chip +5.1 V reference is trimmed to "1% and the error  
amplifier has an input common−mode voltage range that includes the  
reference voltage, thus eliminating the need for external divider  
resistors. A sync input to the oscillator enables multiple units to be  
slaved or a single unit to be synchronized to an external system clock.  
A wide range of deadtime can be programmed by a single resistor

features built−in soft−start circuitry, requiring only an external timing  
capacitor. A shutdown pin controls both the soft−start circuitry and the  
output stages, providing instantaneous turn off through the PWM latch  
with pulsed shutdown, as well as soft−start recycle with longer  
shutdown commands. The under voltage lockout inhibits the outputs
