The function of primary switch is to provide the high frequency necessary to reduce the size of the power supply. The various circuit topologies demand 2 basic characteristics of the HEXFET power MOSFETs used in this socket, low gate charge and low RDS(on). IGBTs used in this socket are fast switching WARP SpeedTM IGBTs with low conduction losses.
Lambdaaa’s line of HEXFET power MOSFET can be categorized by three tiers of performance and the markets they target as follows:
