General Description

DP2545 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.

In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin.

Key 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 package.
