Product Description

KP3210SGA is a high-performance, low-cost offline PWM-controlled power switch IC designed for low-power AC-DC power supply applications. It integrates a 650V high-voltage MOSFET and a high-voltage startup circuit, reducing external component requirements and simplifying power supply design.
The device uses multi-mode PWM control technology to achieve good line/load regulation, high efficiency, and noise-free operation. It supports Buck and Buck-Boost topologies and provides features such as soft-start, green mode operation, and multiple protection mechanisms for reliable system performance.
KP3210SGA is mainly used in compact offline AC-DC adapters, small household appliance power supplies, and auxiliary power supply designs.
