Description

General part information

NCV890430 Series

The NCV890430 is a fixed-frequency Synchronous Buck regulatorintended for Automotive, battery-connected applications that operatewith up to a 45 V input supply. It is suitable for automotive systemsrequiring low noise and low shutdown currents that also need tooperate at low input voltage close to the output voltage. A reset pin(with adjustable delay) simplifies interfacing with a microcontroller.This part also features an enable input that can either be connected to alow voltage (such as a micro-controller output) or high voltage (suchas the battery input), and a synchronization input.The NCV890430 also provides several protection features expectedin automotive power supply systems such as current limit, short circuitprotection, and thermal shutdown. In addition, the high switchingfrequency produces low output voltage ripple even when using smallinductor values and all-ceramic input output filter capacitors −forming a space-efficient switching regulator solution.
