OB2223F High Precision Low Cost MCM Power Switch GENERAL DESCRIPTION OB2223F is a high performance, high precision and low cost PWM Power switch for non-isolated buck and flyback application. It combines a dedicated current mode PWM controller (with a high voltage power MOSFET with SOP8/DIP7 package) and built-in error amplifier optimized for good overshoot and dynamic response for low cost and component count. With precise inner resistor divider, precise reference of EA ， accurate constant voltage regulation 12V at universal AC input can be guaranteed. For high efficiency, oscillator with frequency-reduction and burst mode control is implemented. And EMI performance is achieved with On-Bright proprietary frequency shuffling technique and soft gate driver design.
