MP1494S

High Efficiency 2A, 16V, 500kHz

Synchronous Step-Down Converter

DESCRIPTION

FEATURES

The

MP1494S

high-frequency,



Wide 4.5V-to-16V Operating Input Range

150mΩ/70mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

Fixed 500kHz Switching Frequency

Synchronizes to a 300kHz to 2MHz External

Clock

AAM Power-Save Mode

Internal Soft-Start

OCP Protection and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in an 8-pin TSOT-23 package

synchronous, rectified, step-down, switch-mode

converter with built-in power MOSFETs. It

offers a very compact solution to achieve a 2A

continuous output current with excellent load

and line regulation over a wide input supply

range. The MP1494S 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 MP1494S requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.

APPLICATIONS



Notebook Systems and I/O Power

Digital Set-Top Boxes

Flat-Panel Television and Monitors

Distributed Power Systems
