Desktop power supplies

There are mainly two types of Desktop power supplies, very high power for gaming (also to support mining for cryptocurrency) and the other is enterprise use. Both are using the new X86 CPU, which needs a much higher peak current and higher power now. Infineon’s wide portfolio of semiconductors offers a complete system solution to meet desktop power PSU requirement  and trends: higher power and efficiency.

Our CoolMOS™ high voltage MOSFETs and OptiMOS™ mid and low voltage MOSFETs, to our EiceDRIVER™ gate drivers our CoolSET™ auxiliary SMPS controllers are the best fit for these market trends.

CoolGaN™ and CoolSiC™ technologies offer fundamental advantages over silicon and are designed to enable even higher efficiency and density with robust, high-quality, and reliable products. They exhibit no/very low reverse recovery charge. This allows the use of WBG devices in hard-switched topologies, such as the totem-pole PFC.

CoolSiC™ exhibits the lowest increase of R_dson over temperature, which makes it the prime choice for high-current applications in hard-switched topologies, such as in the Totem-Pole PFC stage.

CoolGaN™ exhibits the lowest Q_g and Q_oss charges, making GaN the preferred choice for soft-switched high frequencies topologies such as the LLC topology.

Our team of experts is ready to share in-depth knowledge about the requirements of today and tomorrow.
