3 Description
The LMR51460-Q1 is a wide-VIN, easy-to-use,
synchronous buck converter capable of driving up
to 6A load current. With a wide input range of 4V
to 36V, the device is designed for a wide range of
industrial applications for power conditioning from an
unregulated source.
The LMR51460-Q1 features adjustable switching
frequency from 200kHz to 1MHz with an external
resistor, which provides the flexibility to optimize either
efficiency or external component size. The device
has 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 allows the device to be
used with minimum 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. The LMR51460-Q1 is available in a
WSON-12 package.
