EPC90152: 100 V, 14 A GaN-based half-bridge development board

Overview

TopologyHalf-Bridge Converter Nonisolated
Input voltage7.5-12 V
Switching frequency500-2000 kHz
Output 114 A
IC revision1.0

Description

The EPC90152 development board is a 100 V maximum device voltage, 14 A maximum output current, half bridge with onboard gate drives, featuring the EPC23104 integrated ePower™ Stage. The purpose of this development board is to simplify the evaluation process of the EPC23104 by including all the critical components on a single board that can be easily connected into most existing converter topologies.The EPC90152 development board is 2” x 2” and contains one EPC23104 integrated ePower™ Stage in a half bridge configuration. The board also contains all critical components, and the layout supports optimal switching performance. There are also various probe points to facilitate simple waveform measurement and efficiency calculation.

Features

  • Integrated high side and low side eGaN FET with internal gate driver and level shifter
  • 5 V external bias supply
  • 3.3 V or 5 V CMOS input logic levels
  • Independent high side and low side control inputs
  • Logic lockout commands both FETs off when inputs are both high at same time
  • External resistors to tune SW switching times and over-voltage spikes above rail and below ground
  • Robust level shifter operating for hard and soft switching conditions
  • False trigger immunity from fast switching transients
  • Synchronous charging for high side bootstrap supply
  • Disable input engages low quiescent current mode from VDRV supply
  • Power on reset for low side VDD supply
  • Power on reset for high side VBOOT supply
  • Active gate pull-down for HS FET and LS FET with loss of VDRV supply
  • Thermally enhanced QFN package with exposed top for low thermal resistance from junction to top-side heatsink

Typical applications

  • Motor Drive Inverter
  • Buck, Boost, Buck-Boost Converters, Half-Bridge, Full Bridge LLC Converters
  • Class D Audio Amplifier
