3 Description
The LMR51403 is a wide-VIN, easy-to-use
synchronous buck converter capable of driving up to
300mA load current. With a wide input range of 4V
to 42V, the device is designed for a wide range of
industrial applications for power conditioning from an
unregulated source.
The LMR51403 operates at 400kHz and 1.1MHz
switching frequency to support use of relatively
small inductors for an optimized design size. The
LMR51403 has a pulse frequency modulation (PFM
version) to realize high efficiency at light load
and forced pulse width modulation (FPWM version)
to achieve constant frequency and small output
voltage ripple over the full load range. Soft-start
and compensation circuits are implemented internally,
which allow the device to be used with minimal
external components.
The device has built-in protection features, such as
cycle-by-cycle current limit, hiccup mode short-circuit
protection, and thermal shutdown in case of excessive
power dissipation.
