Upgrade to myMPS+Product Description
The MP1470B 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 MP1470B 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 MP1470B requires a minimal number of readily available, standard, external components and is available in a compact 6-pin TSOT23 package.
