Overview
SG1525A/SG2525A/SG3525A SG1527A/SG2527A/SG3527A REGULATING PULSE WIDTH MODULATOR DESCRIPTION The SG1525A/1527A series of pulse width modulator integrated circuits are designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies.
The on-chip +5.
1 volt reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors.
A Sync input to the oscillator allows multiple units to be slaved together, or a single unit to be synchronized to an external system clock.
A single resistor between the CT pin and the Discharge pin provides a wide range of deadtime adjustment.
These devices also feature built-in soft-start circuitry with only a timing capacitor required externally.
A Shutdown pin controls both the soft-start circuitry and the output stages, providing instantaneous turn-off with soft-start recycl...
