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.
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.
