MP8706EN集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

DESCRIPTION

The MP8706 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

MP8706 has synchronous mode operation for

higher efficiency over output current load range.

Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include OCP and

thermal shut down.

The MP8706 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.
