DESCRIPTION

The LMR14203 is a PWM DC/DC buck (step-down)

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

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 soft-start time

to a specific application.

The LMR14203 is optimized for up to 300 mA load

current.

Additional features include: thermal shutdown, VIN

under-voltage lockout, and gate drive under-voltage

lockout. The LMR14203 is available in a low profile

SOT-6L package.
