ISL73847SEHDEMO6Z
The ISL73847SEHDEMO6Z demonstration board
demonstrates the performance of two
dual-phase buck controller, four ISL73041SEH GaN
half-bridge drivers, and twelve ISL70020SEH 40V
GaN FETs in a 4-phase, 100A configuration. It is
designed for the VERSAL VC1902 VCCINT core rail.
The evaluation board is designed for a 5V PVIN
power rail and an auxiliary VDD supply for the
controller/driver VDD and on-board clock generator
circuits.
