Automotive 3-A 2-MHz Low-Iq Dual-Mode Step-Down Regulator Evaluation Board

Overview

Evaluation board for the NCV891330 Dual Mode regulator intended for Automotive, battery-connected applications that must operate with up to a 45V 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. This is the 3.3 volt version of the part.
