DP2539B - High Precision CC/CV Primary-Side PWM Power Switch
DP2539B is a high performance offline PWM power switch for low power AC/DC charger and adapter applications.
It operates in primary-side sensing and regulation.
Consequently, opto-coupler and TL431 could be eliminated.
High Precision Constant Voltage (CV) and Constant Current (CC) control are integr
DP2539B Features
* including Cycle-by-Cycle current limiting, VDD Over Voltage Protection (VDD OVP), short circuit protection, built-in leading edge blanking, VDD under voltage lockout (UVLO), OTP, etc. High precision constant voltage (CV) and constant current (CC) can be achieved by DP2539B. DP2539B is offered in DIP
