Overview

OB2372 is an excellent primary side regulation controller with CC/CV operation for medium level power AC/DC charger and adapter applications. The device directly drives a power MOSFET and operates in CCM/QR mode to provide high efficiency along with several functions of built-in protections. It removes the need for secondary feedback circuitry to lower the total bill of material cost. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated. OB2372 is an excellent integrated multi-mode PWM controller optimized for off-line middle power AC/DC applications. It operates in continuous conduction mode (CCM) and quasi-resonant mode (QR) to provide high efficiency with primary side sensing and regulation thus provide cost effective solution for energy efficient power supplies. Proprietary built-in CV and CC control can achieve high precision CC/CV control meeting most charger application requirements.

Applications

Cell phone charger
Tablet PC
AC/DC adapter
Set-top box power supplies
