Overview

OB2273 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. The ‘Extended burst mode’ control greatly reduces the standby power consumption and helps the design easily to meet the international power conservation requirements.

Applications

Battery Charger
Power Adapter
Set-Top Box Power Supplies
Open-frame SMPS
