OB2222M High Precision Low Cost Power Sw itch GENERAL DESCRIPTION OB2222M is a high performance, high precision and lo w cost PWM Power switch for non-isolate d buck and buck-boost application. It c ombines a dedicated current mode PWM co ntroller with a high voltage power Bipo lar in SOP8 package. Its built-in error amplifier is optimized for good oversh oot and dynamic response for low cost a nd component count. With precise inner resistor divider, precise reference of EA , constant voltage regulation of 5 .0V at universal AC input can be guaran teed. Frequency reduction and burst mod e control is implemented for high effic iency at light load. Good E

MI performance is achieved with On-Brigh t proprietary frequency shuffling techn ique and soft base driver design. Low s tartup current and low operating curren t contribute to a reliable power on sta rtup and low standby power consumption with OB2222M. Constant power operation is supported at over load application w ith OB2222M, which makes it suitabl
