New power modules have been added by International Rectifier targeting high efficiency appliance and light industrial applications.
The new devices are available in an very small 8 by 9 by 0.9mm PQFN package, enabling the IRSM808-105MH and IRSM807-105MH half-bridge power modules to offer up to a 60 percent smaller footprint than existing 3-phase motor control power ICs. These devices have been developed for applications including compressor drives for refrigeration, pumps for heating and water circulation, air-conditioning fans, dishwashers, and automation systems.
The IRSM808-105MH and IRSM807-105MH half-bridge µIPM power modules provide designers with even greater scalability, in addition to offering up to a 60 percent smaller footprint compared to existing leading solutions and delivering advantages in output current capability and system efficiency cost-effectively,” said Alberto Guerra, Vice President, Strategic Market Development, IR’s Energy Saving Products Business Unit.
The company advises its µIPM product family are scalable with common pin-out package size, featuring high-voltage FredFET MOSFET switches that are optimised for variable frequency drives. They offer DC current ratings ranging from 2A to 10A and voltages of 250V and 500V. The new approach pioneered by IR for this market segment utilises PCB copper traces to dissipate heat from the module, providing cost savings through a smaller package design and 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.
