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.
