OB2283 High Performance Current Mode PWM Controller GENERAL DESCRIPTION OB2283 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved. VCC low startup current and low operating current contribute to a reliable power on startup and low standby design with OB2283.
