100V GaN E-HEMT Full Bridge Evaluation Board

The GS61004B-EVBCD evaluation board from GaN Systems allows the user to evaluate the company’s GS61004B gallium nitride Enhancement mode-High Electron Mobility Transistors (E-HEMTs) with the Peregrine PE29102 gate driver in a full-bridge configuration.  The outputs of the PE29102 are capable of providing switching transition speeds in the sub nano-second range for hard switching applications.

The evaluation board (EVB) is assembled with two PE29102 GaN E-HEMT drivers and four GS61004B E-HEMT transistors. Headers are included for signal input, signal output, and power connections. Probe points are included for waveform measurements. Provision has been made for a single, suitable heatsink to be fastened against the four E-HEMTs, using the three holes in the center of the board.

GS61004B-EVBCD evaluation board features

  • Operable up to 5MHz
  • Transistor driver operable up to 40MHz
  • Best-in-class propagation delay
  • Optimized, Vcc independent, for matched dead time
  • Integrated dead-time control, resistor-adjustable
