Features: MP1495S High Efficiency 3A, 16V, 500kHz Synchronous Step-Down Converter DESCRI PTION The MP1495S is a high-frequency, synchronous, rectified, step-down, swit ch-mode converter with built-in power M OSFETs. It offers a very compact soluti on to achieve a 3A continuous output cu rrent with excellent load and line regu lation over a wide input supply range. The MP1495S has synchronous mode operat ion for higher efficiency over the outp ut current load range. Current-mode ope ration provides fast transient response and eases loop stabilization. Full pro tection features include over-current p rotection and thermal shut down. The MP 1495S requires a minimal number of read ily-available standard external compone nts, and is available in a space-saving 8-pin TSOT23 package. TYPICAL APPLICAT ION FEATURES  Wide 4.5V-to-16V Oper ating Input Range  120mΩ/50mΩ Low RDS(ON) Internal Power MOSFETs  High -Efficiency Synchronous Mode Operation  Fixed 500kHz Switching Frequency  Synchronizes to a 300kHz to 2MHz E.

MP1495S
High Efficiency 3A, 16V, 500kHz
Synchronous Step-Down Converter
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.
