Description: OB2269C GENERAL DESCRIPTION OB2269C is a highly integrated current mode PWM co ntrol IC optimized for high performance , low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal oper ation is externally programmable and tr immed to tight range. At no load or lig ht load condition, the IC operates in e xtended ‘burst mode’ to minimize sw itching loss. Lower standby power and h igher conversion efficiency is thus ach ieved. VDD low startup current and low operating current contribute to a relia ble power on startup design with OB2269 C. A large value resistor could thus be used in the startup circuit to minimiz e the standby power. The internal slope
