DESCRIPTION

The μPA1809 is a switching device which can be

driven directly by a 4.0 V power source.

This device features a low on-state resistance and

excellent switching characteristics, and is suitable for

applications such as DC/DC Converters and power

management of notebook computers and so on.

FEATURES
