International Rectifier and Infineon Technologies have announced that Infineon will license from International Rectifier its patented advanced power management packaging technology, DirectFET.

Designed for use in AC/DC and DC/DC power conversion applications in computers, notebooks, telecommunications and consumer electronics devices, the DirectFET power package is an industry-first surface-mount power MOSFET packaging technology for efficient topside cooling in an SO-8 footprint or smaller. Compared to standard plastic discrete packages, DirectFET's metal can construction enables dual-sided cooling to effectively double the current handling capacity of high frequency DC-DC buck converters.

"By deploying a unique dual-sided cooling design, IR's DirectFET package technology is the preferred solution to reduce energy losses while shrinking the design footprint in advanced computing, consumer and communications applications," said Tim Phillips, VP of enterprise power business unit at International Rectifier.

Infineon will deploy the DirectFET power package technology with its OptiMOS 2 and OptiMOS 3 chip technology and expects to sample the OptiMOS 2 in DirectFET packages starting early 2008.

"Combining our successful OptiMOS chip technology with various package options suited for a wide range of applications, we enable power supply designers achieve energy and cost-efficient solutions for a given application," said Arunjai Mittal, senior VP and general manager of the power management and drives business unit at Infineon Technologies. "Providing OptiMOS 2 and OptiMOS 3 devices with their excellent characteristics in a package with double-sided cooling capability will further strengthen Infineon's position in the power conversion market."
