µIPM power modules from IR to deliver efficient motor control solutions

IR has introduced a family of integrated, 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.

IR's µIPM product family offers a scalable power solution with common pin-out and package size. Available in a compact 12x12x0.9 mm PQFN package, the µIPM family comprises a series of fully integrated 3-phase surface-mount motor control circuit solutions. They also offer DC current ratings ranging from 2A to 4A and voltages of 250V and 500V.

"By utilizing an innovative packaging solution, IR's µIPM products not only offer up to 60 percent smaller footprint compared to existing leading solutions but also deliver advantages in output current capability and system efficiency. Combined with ease of use, improved thermal performance and overall system size reduction, the µIPM family enables designers and system integrators to deliver more cost effective and advanced motor control solutions," said Alberto Guerra, VP, strategic market development, IR's energy saving products business unit.
