MP8716

High Efficiency 3A, 21V, 500kHz

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP8716 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 over a wide input supply range

with excellent load and line regulation. The

MP8716 has synchronous mode operation for

higher efficiency over output current load range.

•

Wide 4.5V to 21V Operating Input Range

3A Output Current

Low Rds(on) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

High Efficiency Synchronous Mode Operation

Fixed 500kHz Switching Frequency

Sync from 300kHz to 2MHz External Clock

1.5ms Internal Soft-Start Time

Internal Compensation

OCP Protection and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in a Thermally Enhanced 8-pin SOIC

package

•

Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include OCP and

thermal shut down.

The MP8716 requires a minimum number of

readily available standard external components

and is available in a space saving 8-pin SOIC

package with an exposed pad.

APPLICATIONS

•

Notebook Systems and I/O Power

Networking Systems

Digital Set Top Boxes
