Development Board EPC9148 Quick Start Guide:48 V Three-level Synchronous Buck Converter, Using EPC2053

2023-06-13
●DESCRIPTION
■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.
■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 uP1966E 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.
