Introduction

AI Translation

OB2632 is a highly integrated current mode PWM control IC with high voltage startup, optimized for high performance, low standby power consumption and wide output voltage range PD adapter solutions, together with PD secondary controller, such as OB2612. The controller is as well compatible with cost effective offline flyback converter applications covering a wide output range. The ‘Extended burst mode’ control greatly reduces the standby power consumption and helps the design easily to meet the international power conservation requirements.
