Overview

TopologyHalf-Bridge Converter symmetrical isolated
IC revision1.0

Description

The STEVAL-G0807LBCB is designed for evaluating the electrical and thermal characteristics of the SGT080R70ILB 700-V e-mode PowerGaN transistor using the isolated gate driver STGAP2GS.The half-bridge configuration enables the emulation of buck, boost, PFC, and inverter topologies with a dedicated external controller and filtering.The STEVAL-G0807LBCB is optimized to reduce voltage undershoots and overshoots while ensuring fast switching times.As the PowerGaN switches are mounted on the top side of the FR4 PCB, it facilitates the evaluation of different thermal interface materials (TIM), enabling the PowerGaN to deliver maximum power with an efficient thermal interface.The SGT080R70ILB is a 60 mΩ typ, 700 V, 29 A e-mode GaN power transistor combined with an innovative PowerFLAT 8x8 HV bottom-side cooling packaging technology. This device provides low conduction losses, high current capability, and ultrafast switching operation, enabling high-power density and efficiency performance.The PowerGaN transistor is controlled by the STGAP2GS, a galvanically isolated 3 A single gate driver for enhancement-mode GaN FETs. The board allows independent optimization of turn-on and turn-off by using dedicated gate resistors.

Features

  • Half-bridge topology featuring 600 V peak voltage
  • Equipped with 700 V, 60 mΩ typ., 29 A, e-mode PowerGaN transistor
  • Bottom solder mask aperture for high heat-sink performance
  • 8°C/W junction-to-board thermal resistance
  • -3.0/+6.2 VCC gate driver supply voltage
  • On-board adjustable deadtime generator to convert single PWM signals into independent high-side and low-side signals with deadtimes from 10 to 150 ns
  • Dedicated input connector for external deadtime PWMs
  • Up to 1 MHz switching frequency operation
  • MMCX high frequency connector for high side GaN gate voltage measurement
  • 5.08 mm pitch for GaN drain-source voltage monitoring
  • Optional low-side shunt for transistor source current monitoring

Typical applications

  • Power supplies and converters, AC-DC and DC-DC converters
