SG3525A SMD MOSFET SOP16 3525 ST SG3525A

Product Overview

A surface-mount pulse width modulator (PWM) control integrated circuit (IC) designed to drive power MOSFETs in switching power supplies. It features dual alternating outputs, making it ideal for push-pull, half-bridge, and full-bridge inverter configurations.

Note: Despite generic online listing titles that include the term "MOSFET," this component is functionally a PWM Controller IC used to control power transistors, rather than a standalone transistor.
