If you want to design a compact and efficient DC-DC converter, then this reference design is suitable for you. The EPC9048C is a half bridge development board with onboard gate driver. This reference design features an EPC2034C GaN FET that is rated for 200V. The design can be easily set up as a buck or boost converter. The board measures 2” x 2” and contains two GaN FETs in a half bridge configuration. The reference design employs a On-Semi NCP51820 gate driver along with all critical components and the layout to support optimal switching performance.
The performance characteristics of the reference design is given below:
The reference design can be used as a evaluation board for the GaN FETs as the design contains various probe points to facilitate simple waveform measurement and efficiency calculation. The block diagram of the circuit is given below:
The board can be operated in a buck converter or a boost coverter topology by selecting the appropriate jumper setting, moreover both the topologies can be used in a single or dual PWM inputs which can be chosen using the appropriate jumper settings on J630.
The company has provided various design resources including application notes, gerber files, schematic sketch, etc. To learn more about this reference design visit https://epc-co.com/epc/products/demo-boards/epc9048c
