Description:

ANALOG PWM

Features

* including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO.

Applications

* up to 16W. It operates in primary-side regulation. Consequently, opto-coupler and tl431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown In the Fig.1. In CC control,the current and output power setting can be adjusted externally by the se
