MP1470GJ-Z 开关式稳压器

DESCRIPTION

The MP1470 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 MP1470 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 MP1470 requires a minimal number of readily-available,  standard,  external components and is available in a space-saving 6-pin TSOT23 package.
