Overview

OB2223 High Precision Low Cost MCM Power Switch GENERAL DESCRIPTION OB2223 is a high performance, high precision and low cost PWM Power switch for Non-isolated buck/ buck-boost and flyback application.
It combines 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 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 w...
