NCV891330

3 A, 2 MHz Low-I_QDual-

Mode Step-Down Regulator

for Automotive

The NCV891330 is a Dual Mode regulator intended for Automotive,

battery−connected applications that must operate with up to a 45 V

input supply. Depending on the output load, it operates either as a PWM

Buck Converter or as a Low Drop−Out Linear Regulator, and is suitable

for systems with low noise and Low Quiescent Current requirements

often encountered in automotive driver information systems. A reset

pin (with fixed delay) simplifies interfacing with a microcontroller.

The NCV891330 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 an all−ceramic output filter capacitor – forming a

space−efficient switching regulator solution.
