SIMPLE SWITCHER® 4-V to 40-V, 1-A step-down converter With high efficiency eco-mode | DDC | 6 | -40 to 125

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).
