Infineon and Fairchild Semiconductor announced the extension of their compatibility partnership to encompass Infineon’s proprietary 5x6 power stage asymmetric dual MOSFET package. Infineon’s PowerStage 5x6 is a leadless SMD package, which integrates the low-side and high-side MOSFET of a synchronous DC/DC converter into a 5x6mm² package outline. This allows reduction in design area by up to 85%. The package also minimizes loop inductance and thereby achieves a peak efficiency of 93.5%.

This extended collaboration which began in 2010 is intended to provide customers supply chain security while balancing the drive towards best-in-class efficiency and thermal performance in DC-DC buck conversion. It takes advantage of the expertise both companies offer in asymmetric dual MOSFETs which can handle over 30A and increase power density.
