Description
General part information
LMR14010A Series
The LMR14010A is a PWM DC-to-DC buck (step-down) 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 voltage. Soft-start and compensation circuits are implemented internally, limiting the number of external components.
The LMR14010A is optimized for up to 1A load current. The device has a 0.765V nominal feedback voltage.
The device has built-in protection features such as pulse-by-pulse current limit, thermal sensing and shutdown due to excessive power dissipation. The LMR14010A is available in a low profile TSOT-6L package (2.9mm × 1.6mm × 0.85mm).
