0.6 A 2 MHz 100% Duty Cycle

Step‐Down Synchronous

Regulator for Automotive

The NCV890430 is a fixed-frequency Synchronous Buck regulator

intended for Automotive, battery-connected applications that operate

with up to a 45 V input supply. It is suitable for automotive systems

requiring low noise and low shutdown currents that also need to

operate 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 a

low voltage (such as a micro-controller output) or high voltage (such

as the battery input), and a synchronization input.

The NCV890430 also provides several protection features expected

in automotive power supply systems such as current limit, short circuit

protection, and thermal shutdown. In addition, the high switching

frequency produces low output voltage ripple even when using small

inductor values and all-ceramic input output filter capacitors −

forming a space-efficient switching regulator solution.
