DP2540A High Precision CC/CV Primary-Side PWM Power Switch

DP2540A Description

DP2540A High Precision CC/CV Primary-Side PWM Power Switch GENERAL .
DP2540A is a high performance offline PWM power switch for low power AC/DC charger and adapter applications.

DP2540A 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 DP2540A. DP2540A is offered in DIP

DP2540A 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 externa
