DESCRIPTION
The MP1495S is a high-frequency,
synchronous, rectified, step-down, switch-mode
converter with built-in power MOSFETs. It
offers a very compact solution to achieve a 3A
continuous output current with excellent load
and line regulation over a wide input supply
range. The MP1495S has synchronous mode
operation for higher efficiency over the output
current load range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Full protection features include over-current
protection and thermal shut down.
The MP1495S requires a minimal number of
readily-available standard external components,
and is available in a space-saving 8-pin
TSOT23 package.
