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.
