The Future of Analog IC Technology
The MP1474 is a high-f requency, synchronous,
rectified, st ep-down, switch-mode converter
with built-in power MOSFETs. It o ffers a very
compact solution to achieve a 2A continuous
output curr ent with e xcellent loa d and line
regulation o ver a wide input supply range. The
MP1474 ha s synchronous mode operation fo r
higher efficiency over t he output current load
Current-mode operation provides fast transien t
response and eases loop stabilization.
Full protection feature s include over-current
protection and thermal shut down.
The MP147 4 requires a minimal number of
readily-available standard external components,
and is available in a space- saving 8-pin
