Product details
The implementation of the SG3525A and SG3527A pulse width modulator control circuits for managing all varieties of switching power supply results in increased performance and a reduced exterior parts count. There is no need for external divider resistors because the error amplifier’s input common-mode voltage range encompasses the reference voltage and the on-chip +5.1 V reference is cut to 1%. One unit can be synchronized to an external system clock or several units can be slaved to it using the the oscillator’s sync input. A single resistor linked between the CT and Discharge pins can be used to design a broad range of deadtime. These gadgets also include integrated soft-start circuitry that simply needs an external timing capacitor to function. An instantaneous turn-off via the PWM latch with pulsing shutdown is provided by the soft-start circuitry, which is controlled by a shutdown pin.
