Overview
OB2222M High Precision Low Cost Power Switch GENERAL DESCRIPTION OB2222M is a high performance, high precision and low cost PWM Power switch for non-isolated buck and buck-boost application.
It combines a dedicated current mode PWM controller with a high voltage power Bipolar in SOP8 package.
Its built-in error amplifier is optimized for good overshoot and dynamic response for low cost and component count.
With precise inner resistor divider, precise reference of EA ， constant voltage regulation of 5.
0V at universal AC input can be guaranteed.
Frequency reduction and burst mode control is implemented for high efficiency at light load.
Good EMI performance is achieved with On-Bright proprietary frequency shuffling technique and soft base driver design.
Low startup current and low operating current contribute to a reliable power on startup and low standby power consumption with OB2222M.
Constant power operation is supported at over load application with OB2222M, which makes it suitabl...
