BCT8320S

Green Mode PWM Controller

General Description

The BCT8320S is a high-performance current mode PWM controller which is able to sweep the switching frequency down to 1.5kHz to reduce the power consumption significantly during standby mode. BCT8320S is enhanced with thermal shunt down feature and programmable trip point. Over temperature protection by continuously monitoring the operation temperature inside the chassis is an attractive feature to increase the long term reliability of power supply products.
