OB2268 OB2269 Current Mode PWM Controller OB2268, 9 is offered in SOP-8 and DIP-8 packages. GENERAL DESCRIPTION OB2268, 9 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in above 20W power level. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize
