EPC9148 Development Board

PublishTime：2021-04-20

The EPC9148 demonstration board is a 60 V maximum input voltage,12.5 A maximum output current,19 V output voltage, ultra-thin three-level synchronous buck converter with only a 3.5 mm component height. It features the 40 V EPC2055 and the 100 V EPC2053 and EPC2038 GaN FETs.The purpose of this demonstration board is to simplify the evaluation of GaN FET-based multi-level synchronous buck converter.For more information on the GaN-based multilevel topology please see How 2 AppNote 015:How to Design an Ultra-thin,Highly Efficient,Multilevel DC-to-DC Converter.
A simplified block diagram of the EPC9148 development board is shown in Figure 1. It contains one EPC2053 for Q1, three EPC2055 for Q2-Q4 in the power stage, and three EPC2038 GaN FETs for the synchronous bootstrap gate drive circuits with the uPI Semiconductor uP1966A gate drivers.The board also includes on-board house keeping power supply,digital controller,current and voltage sensing,and output filter. Kelvin sensing test points of the input and output voltages are provided for accurate efficiency measurement.
