Description
The LMR14010A is a PWM DC-to-DC buck (step-down) regulator. With a wide input range from 4 V to 40 V, it is suitable for a wide range of applications from industrial to automotive. An ultra-low 1-µA shutdown current prolongs battery life. Operating frequency is fixed at 0.7 MHz, 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 1-A load current. It has a 0.765-V 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 (2.9 mm × 1.6 mm × 0.85 mm).
