SG3525AP Description
When employed in the design of all types of switching power supplies, the SG3525AP is a regulating pulse width modulator IC that is designed to deliver increased performance and reduced exterior 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. Multiple units can be slaved or synchronized to an external system clock using a synchronized input to the oscillator. 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. SG3525AP applications are as follows:
SG3525AP Features
Internal soft-start
8 to 35 V oepration
Pulse-by-pulse shutdown
Adjustable deadtime control
Dual source/sink output drivers
Separate oscillator sync terminal
5.1 V reference trimmed to ± 1 %
100 Hz to 500 KHz oscillator range
Latching PWM to prevent multiple pulses
Input undervoltage lockout with hysteresis
