OB2365E Datasheet | On-Bright

Adaptive Multi-Mode PWM Controller GENERAL DESCRIPTION OB2365E 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. When the loading goes low, it operates in PFM mode with valley switching for high power conversion efficiency. When the load is very small, the IC operates in ‘Extended Burst Mode’ to minimize the standby power loss. Additionally, in the low line input voltage, the IC operates in...
