EPC23102 – ePower™ Stage IC
VIN , 100 V
EFFICIENT POWER CONVERSION
ILoad , 35 A
PRELIMINARY HAL
The ePowerTM Stage IC Product Family integrates input logic interface, level shifting, bootstrap charging and gate drive buffer circuits along with eGaN output FETs. Integration is implemented using EPC’s proprietary GaN IC technology. The end result is a Power Stage IC that translates logic level input to
