Traditional interior permanent magnet (IPM) solutions for the 30W to 200W inverterised motor-drive market require either a large construction or use of an external heatsink. International Rectifier's alternative approach uses PCB copper traces to dissipate heat from the module. As a result, it has a smaller package design and can eliminate an external heatsink.

Most modern MCUs have more than one low-power mode, ranging from a light sleep or standby mode through deep-sleep to off. However, the power savings available from lower-energy sleep modes come at a price. Energy Micro's Anders Guldahl explains how to optimise a design by finding the lowest power sleep mode that provides an adequate response time.
