3 Description
The LMR516xx-Q1 is a wide-V
IN
, 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 65V, the device is designed for a wide range of
industrial applications for power conditioning from an
unregulated source.
The LMR516xx-Q1 operates at 400kHz switching
frequency to support use of relatively small inductors
for an optimized design size. The LMR516xx-Q1
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.
