SG3525A IC PWM regulator ST DIP-16 SG3525A

Product Overview: The SG3525A is a pulse width modulator (PWM) control circuit designed to improve performance and reduce external parts count in the design of various switching power supplies. The device features an internally trimmed 5.1V reference, an error amplifier with an input common-mode range that includes the reference voltage, and a sync input for external clock synchronization. It includes comprehensive control features such as programmable deadtime, built-in soft-start circuitry, and an under-voltage lockout that inhibits output stages during low-voltage conditions. The output stages are totem-pole configured, capable of sinking and sourcing over 200 mA, and utilize NOR logic to provide a low output in the off-state.
