OB2226 Overview
OB2226 is a high performance, high precision and low cost PWM Power switch for non-isolated buck application. It bines a dedicated current mode PWM controller (with a high voltage power MOSFET with DIP7 package) and built-in error amplifier for low cost and ponent count. With precise inner resistor divider, precise reference of EA and load pensation, accurate constant voltage regulation at universal AC input can be...
