DESCRIPTION
The MP1471A is a high-frequency,
synchronous, rectified, step-down, switch-mode
converter with internal power MOSFETs. It
offers a very compact solution to achieve a 3A
output current over a wide input supply range,
with excellent load and line regulation. The
MP1471A has synchronous-mode operation for
higher efficiency over the output current-load
range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Protection features include over-current
protection and thermal shutdown.
The MP1471A requires a minimal number of
readily-available, standard, external
components and is available in a space-saving
6-pin TSOT23 package.
