Beschreibung

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.
