SG2525A and SG3525A are regulating pulse width modulator integrated circuits. They operate at a voltage range of 8V to 35V, with a 5.1V reference voltage trimmed to ±1%. The oscillator range is from 100Hz to 500kHz. They feature adjustable deadtime control, internal soft-start, pulse-by-pulse shutdown, and other characteristics.
The SG2525A and SG3525A series of regulating pulse width modulator integrated circuits are designed for use in switching power supplies. Key features include an on-chip +5.1 V reference trimmed to ±1%, an oscillator range from 100 Hz to 500 kHz, and separate oscillator sync terminals for synchronization.
