DESCRIPTION
component that provides a cost-effective solution in many indus-
trial applications. The MP111 offers outstanding performance
that rivals much more expensive hybrid components yet has a
footprint of only 4 sq in. The MP111 has many optional features
such as four-wire current limit sensing and external compensa-
tion. The 500 kHz power bandwidth and 15 amp continuous
and 50A pulse output of the MP111 makes it a good choice
for piezo transducer drive applications. The MP111 is built on
a thermally conductive but electrically insulating substrate that
can be mounted to a heat sink.
