4 Description

The LMR14206 is a PWM DC/DC buck (step-down)

regulator. With a wide input range from 4.5V-42V,

they are suitable for a wide range of applications

such as power conditioning from unregulated

sources. They feature a low RDSON (0.9Ω typical)

internal switch for maximum efficiency (85% typical).

Operating frequency is fixed at 1.25 MHz allowing the

use of small external components while still being

able to have low output voltage ripple. Soft-start can

be implemented using the shutdown pin with an

external RC circuit allowing the user to tailor the softstart

time to a specific application.

The LMR14206 is optimized for up to 600 mA load

current with a 0.765V nominal feedback voltage.

Additional features include: thermal shutdown, VIN

under-voltage lockout, and gate drive under-voltage

lockout. The LMR14206 is available in a low profile 6-

pin SOT package.
