MP1499

High Efficiency 5A Peak, 16V, 500kHz

Synchronous Step Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP1499 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 5A peak

output current over a wide input supply range

with excellent load and line regulation. The

MP1499 has synchronous mode operation for

higher efficiency over output current load range.



Wide 4.5V to 16V Operating Input Range

70mΩ/25mΩ Low R_DS(ON)Internal Power

MOSFETs

Proprietary Switching Loss Reduction

Technique

Fixed 500kHz Switching Frequency

Sync from 200kHz to 2MHz External Clock

AAM Power Save Mode

External Soft Start

OCP Protection and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in a QFN10 (2x3mm) Package



Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over current

protection and thermal shut down.

The MP1499 requires a minimum number of

readily available standard external components

and is available in a space saving 10-pin QFN

(2x3mm) package.

APPLICATIONS



Digital Set Top Boxes

Flat Panel Television and Monitors

Distributed Power Systems
