The MP9943 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter
with built-in power MOSFETs. It offers a very
compact solution to achieve a 3A peak output
current with excellent load and line regulation
over a wide input supply range. The MP9943
has synchronous mode operation for higher
efficiency over the output current load range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Full protection features include over-current
protection and thermal shutdown.
The MP9943 requires a minimal number of
readily-available standard external components,
and is available in a space-saving QFN-8
(3mmx3mm) package.
