LMR14010A - Texas Instruments

LMR14010A 1-A Step-Down Converter

The LMR14010A is a PWM DC-to-DC buck (stepdown) regulator. With a wide input range from 4V to 40V, the device is deigned for a wide range of applications from industrial to automotive. An ultra-low 1µA shutdown current prolongs battery life. Operating frequency is fixed at 0.7MHz, allowing the use of small external components while minimizing output ripple .
