The Future of Analog IC Technology
DESCRIPTION
The MP1470H is a high-frequency,
synchronous, rectified, step-down, switch-mode
converter with internal power MOSFETs. It
offers a very compact solution to achieve a 2A
continuous output current over a wide input
supply range, with excellent load and line
regulation. The MP1470H 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 MP1470H requires a minimal number of
readily-available,
standard,
external
components and is available in a space-saving
6-pin TSOT23 package.
