MOSFETs shave DC/DC losses another 10 percent

El Segundo, Calif. – International Rectifier says its newest DirectFET power MOSFET primary-side switches, the IRF6668 80-volt and IRF6662 100-volt devices, can cut power losses at the system level by as much as 10 percent over “enhanced SO-8” devices in medium-power (200 watt) DC/DC bus converter applications.
