EPC9048 - Development Board

EPC9048 : 160 V Half-Bridge Development Board

EPC Development Board

The EPC9048 development boards are in a half bridge topology with onboard gate drives, with a 12 A maximum output current, featuring the EPC2034 enhancement mode (eGaN®) field effect transistor (FET). The development board contains two eGaN FETs in a half bridge configuration using the Texas Instruments UCC27611 gate driver, supply and bypass capacitors. The board contains all critical components and layout for optimal switching performance. There are also various probe points to facilitate simple waveform measurement and efficiency calculation.

* Assumes inductive load, maximum current depends on die temperature – actual maximum current will be subject to switching frequency, bus voltage and thermal management.
# Dependent on time needed to ‘refresh’ high side bootstrap supply voltage.
