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

connected between the C and Discharge pins. This device also

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

and the changing of the soft−start capacitor when V

is below

nominal. The output stages are totem−pole design capable of sinking

and sourcing in excess of 200 mA. The output stage of the SG3525A

features NOR logic resulting in a low output for an off−state.
