Datasheet Summary
OB2235x
High Precision Low Cost Power Switch
GENERAL DESCRIPTION
OB2235x is a high performance, high precision and low cost PWM Power switch for non-isolated buck and buck-boost application. It bines a dedicated current mode PWM controller with a high voltage power Mosfet in DIP7,DIP8&SOP8 package. Its built-in error amplifier is optimized for good overshoot and dynamic response for low cost and ponent count. With precise inner resistor divider, precise reference of EA, constant voltage regulation of 12V 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...
