NCV891130 Step-Down Regulator Automotive, Low-Iq, Dual-Mode 1.2 A, 2 MHz The NCV891130 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 NCV891130 also provides several protection features expected in automotive power supply systems such as current limit, short circuit protection, and thermal shutdown.
