3 Description
The LMR514xx is a wide-VIN, easy-to-use
synchronous buck converter capable of driving up to
0.6A and 1A 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 LMR514xx operates at 400kHz and 1.1MHz
switching frequency to support use of relatively
small inductors for an optimized design size. The
LMR514xx has a PFM version to realize high
efficiency at light load and a 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.
