OB2223 Overview
OB2223 is a high performance, high precision and low cost PWM Power switch for Non-isolated buck/ buck-boost and flyback application. It bines a dedicated current mode PWM controller (with a high voltage power MOSFET with SOP8/DIP8 package) and built-in error amplifier optimized for good overshoot and dynamic response for low cost and ponent count. With precise inner resistor divider, precise reference of EA ，...
