NX2309 - Microsemi

NX2309 SINGLE SUPPLY 12V SYNCHRONOUS PWM CONTROLLER

FEATURES The NX2309 controller IC is a combination synchronous n 12V PWM controller plus LDO controller Buck and LDO controller IC designed to convert single n Fixed hiccup current limit by sensing Rdson of 12V supply to low cost dual on board supply applica- MOSFET tions. The synchronous controller is used for high cur- n 12V high side and low side driver.
