The EVIC420 evaluation board is a general-purpose circuit board designed to simplify the evaluation of the DEI DEIC420 gate drive IC, as well as to provide a building block for power circuit development. The DEIC420 RF-package gate driver is factory-installed in the EVIC420. The option A board enables the user to drive MOSFETs in the DEI DE150 or DE-275 RF package types, and the Option B board driver DE-375 and DE-475 package type MOSFETs. The evaluation board design allows both the DEIC420 and the MOSFET to be attached to a heat sink, and in so doing the board assembly can be used as a ground referenced, low side power switch for both single-ended and push-pull configurations.
