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 compensation. 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.
