OB2365A Overview
OB2365A is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. At normal load condition, it operates in QR mode in high line input voltage. To minimize switching loss, the maximum switching frequency in QR mode is internally limited to 77 KHz.
