NCV890430 Step-Down Synchronous Regulator

Pin No. Pin Name Description 1 VIN Input voltage from battery. Place an input filter capacitor in close proximity to this pin. 2 RSTB Reset reporting flag. Open drain output, pulling down to ground when the output voltage is out of regulation. The value of the external pull-up resistor de.

NCV890430 Synchronous Regulator Automotive, Step‐Down, 100% Duty Cycle 0.6 A, 2 MHz 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.

NCV890430 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
