The Future of Analog IC Technology
The MP1497S is a high-frequency,
synchronous, rectified, step-down switch mode
converter with built in internal power MOSFETs.
It offers a very compact solution to achieve 3A
continuous output current with excellent load
and line regulation over a wide input supply
range. The MP1497S has synchronous mode
operation for higher efficiency over the output
current load range.
Current-mode operation provides a fast
transient response and eases loop stabilization.
Protective features include over-current
protection, thermal shutdown, and external SS
The MP1497S requires a minimal number of
readily-available external components and is
available in a space-saving 8-pin TSOT23
