DP2539B High Precision CC/CV Primary-Side PWM Power Switch

DP2539B Description

DP2539B High Precision CC/CV Primary-Side PWM Power Switch GENERAL .
DP2539B is a high performance offline PWM power switch for low power AC/DC charger and adapter applications.

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

DP2539B 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 integrated as shown in the figure below. In CC control, the current and output power setting can be adjusted exter
