DP2539 DIP8 PWM Power Switch IC

DP2539 DIP8 PWM Power Switch IC

DP2539A 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 integrated as shown in the figure below.DP2539A offers comprehensive protection coverage with auto-recovery 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.
