SG3525 (3525) Pulse Width Modulation Controller IC SOIC16-W SMD Package

SG3525 (3525) Pulse Width Modulation Controller IC SOIC16-W SMD Package 

The SG3525 is a widely used pulse width modulation (PWM) controller IC designed for switch-mode power supplies (SMPS), DC-DC converters, inverters, and motor control applications. It integrates a complete PWM control circuit with dual totem-pole outputs, enabling efficient driving of power MOSFETs or IGBTs. The SOIC-16 wide (SOIC-16W) SMD package makes it suitable for compact, surface-mount designs.
