Development Board EPC9148 Quick Start Guide

PublishTime：2020-11-23

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 3.5 mm component height. It features the 40 V EPC2055 and the 100 V EPC2053 and EPC2038GaN FETs. The purpose of this demonstrate 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 How2AppNote 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 housekeeping 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. For more information on EPC2055, EPC2053 and EPC2038, please refer to the datasheet available from EPC at epc-co.com. The datasheet should be read in conjunction with this quick start guide.
