EPC90155: 40 V, 10 A Half-Bridge Evaluation Board
The EPC90155 is a half bridge evaluation board with onboard gate driver, featuring the 40 V rated
EPC2057 eGaN® FET. The purpose of this
evaluation board is to simplify the evaluation process of the EPC2057 by including all the critical
components on a single board that can be easily integrated into most existing converter topologies.
The EPC90155 evaluation board measures 2” x 2” and contains two
EPC2057 eGaN FETs in a half bridge configuration
and one EPC2038 GaN FET used to augment the
bootstrap supply. The EPC90155 features the uPI Semiconductor uP1966E gate driver. The board contains
all critical components, and the layout supports optimal switching performance. There are also various
probe points to facilitate simple waveform measurement and efficiency calculation. A block diagram of
the circuit is given in figure 1.
