OB2222M Datasheet | On-Bright

DESCRIPTION FEATURES OB2222M is a high performance, high precision - Universal AC input range and 5.0V output and low cost PWM Power switch for non-isolated voltage buck and buck-boost application. It bines a - Constant power mode operation at over load dedicated current mode PWM controller with a application high voltage power Bipolar in SOP8 package. Its - Low cost and less BOM for buck and buck- built-in error amplifier is optimized for good boost applications overshoot and dynamic response for low cost and ponent count. With precise inner resistor divider, precise reference of EA ， constant voltage regulation of 5.0V at universal AC input - Current mode control - 40k Hz (typical) maximum switching frequency - Frequency-reduction and burst mode control for high efficiency 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...
