NCV891130 شرح
NCV891130
1.2 A, 2 MHz Low-IQ Dual-
Mode Step-Down Regulator
for Automotive
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. 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.
