MP8670
The Future of Analog IC Technology
MP8670
6A, 30V, 420KHz Step-Down Converter
with Synchronizable Gate Driver
DESCRIPTION
The MP8670 is a monolithic step-down switch
mode converter with a built-in internal power
MOSFET. It achieves 6A continuous output
current over a wide input supply range with
excellent load and line regulation.
Current mode operation provides fast transient
response and reliable over-current protection.
The MP8670 requires a minimum number of
readily available standard external components
and is available in an 8-pin SOIC package with
exposed pad.
