General Description

The highly integrated SG6902 is designed for power supplies with boost PFC and Flyback PWM.

It requires very few external components to achiev

Overview

Product Specification Green-Mode PFC / Flyback-PWM Controller www.DataSheet4U.com SG6902 The patented interleave-switching feature synchronizes the PFC and PWM stages and reduces switching noise.

At light loads, the switching frequency is continuously decreased to reduce power consumption.

If output loading is further reduced, the PFC stage is turned off to further reduce power consumption.

Key Features

Green-mode PFC and PWM operation No switching of PFC at light loads saves power Low start-up and operating current Innovative switching-charge multiplier-divider Multi-vector control for improved PFC output transient response Interleaved PFC/PWM switching Programmable two-level PFC output voltage Average-current-mode control for PFC Cycle-by-cycle current limiting for.
