DP2545 High Precision CC/CV Primary-Side PWM Power Switch

DP2545 Description

DP2545 High Precision CC/CV Primary-Side PWM Power Switch GENERAL .
DP2545 is a high performance offline PWM power switch for low power AC/DC charger and adapter applications.

DP2545 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 DP2545. DP2545 is offered in DIP7

DP2545 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
