International Rectifier (IR) announces a family of highly integrated, ultra compact, patent pending µIPM power modules for high-efficiency appliance and light industrial applications, including compressor drives for refrigeration, pumps for heating and water circulation, air-conditioning fans, dishwashers, and automation systems. By utilizing innovative packaging, the µIPM family delivers a 60% smaller footprint than existing 3-phase motor control power ICs.

Available in an ultra compact, 12 x 12 x 0.9-mm PQFN package, the µIPM family comprises a series of fully integrated 3-phase surface-mount motor control circuit solutions. IR's design approach utilizes PCB copper traces to dissipate heat from the module, providing cost savings through a smaller package design and even eliminating the need for an external heat sink. By using standard packaging QFN technology, assembly is simplified by eliminating through-hole second pass assembly and improving thermal performance compared to traditional dual-in-line module solutions.

IR’s µIPM product family offers a scalable power solution with common pin-out and package size. Featuring rugged and efficient high-voltage FredFET MOSFET switches optimized for variable frequency drives and advanced high-voltage driver ICs, the µIPM product family offers dc current ratings from 2 to 4 A and voltages of 250 and 500 V.
