The Future of Analog IC Technology
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
