OB2362D Multi-Mode PWM Controller GENERAL DESCRIPTION OB2362D is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. At full loading, the IC operates in fixed frequency (65KHz) mode. When the loading goes low, it operates in Green 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. As a result, high conversion efficiency can be achieved in the whole loading range. VCC low startup current and low operating current contribute to a reliable power on startup and low standby design with OB2362D.
