OB2734D Overview
OB2734x is a highly integrated current mode PWM controller with a 650V GaN FET integrated. It is optimized for high performance, low EMI, low standby power consumption and wide output voltage range PD adapter solutions, together with PD secondary controller, such as OB2623. The controller is as well patible with cost effective offline flyback converter applications covering a wide output range.
