40 V Half-bridge with Gate Drive, Using EPC2067 Revision


TopologieGegentaktwandler (Halbbrücken)
Eingangsspannung32 V
Ausgang 140 A


The EPC90138 is a half bridge development board with onboard gate drives, featuring the 40 V rated EPC2067 GaN field effect transistor (FET). The purpose of this development board is to simplify the evaluation process of the EPC2067 by including all the critical components on a single board that can be easily connected into the majority of existing converter topologies.The EPC90138 development board measures 2” x 2” and contains two EPC2067 GaN FET in a half bridge configuration and one EPC2038 GaN FET used to augment the bootstrap supply. The EPC90138 features the uPI Semiconductor uP1966E gate driver. The board also 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.For more information on EPC2067 please refer to their datasheets available from EPC at www.epc-co.com. The datasheet should be read in conjunction with this quick start guide.
