SG3525AN Description
:
When employed in the design of all types of switching power supplies, the SG3525AN is a regulating pulse width modulator IC that is designed to deliver increased performance and reduced external parts count. The on-chip 5.1V reference is cut to 1%, and the error amplifier's input common-mode range covers the reference voltage, removing the need for additional resistors. Between the CT and the discharge terminals, a single resistor allows for a wide range of dead time adjustment. This gadget also includes soft-start circuitry, requiring only an external timing capacitor. With pulsed shutdown, a shutdown terminal controls both the soft-start circuitry and the output stages, allowing for fast turn-off via the PWM latch as well as soft-start recycle with longer shutdown orders.
