Texas Instruments LMG3650EVM Daughter Card Evaluation Modules

Texas Instruments LMG3650EVM Daughter Card Evaluation Modules support two LMG3650R025 650V GaN FETs with an integrated driver and protection in a half-bridge configuration with all the required bias circuits and logic/power level shifting. The device provides essential power stage and gate-driving, with high-frequency current loops fully enclosed on the board to minimize power loop parasitic inductance. The TI LMG3650EVM is designed for a socket-style external connection that easily interfaces with external power stages to run the LMG3650R025 in various applications.

Features

  • Two TI 650V GaN in TOLL package arranged in half-bridge configuration
  • Digital isolators for high-side fault signal
  • Isolated bias supply and bootstrap supply option
  • Isolated gate driver and open component positions for layout compatibility to evaluate integrated GaN TOLL and discrete GaN TOLL
  • Heat sink with fan attached for heat dissipation during testing
  • Fault protection and reporting for over temperature, overcurrent, and short circuit events
  • Standard daughter card pinout for compatibility with TI GaN motherboards
  • Absolute maximum voltage rating of 650V

Applications

  • Merchant network and server PSU
  • Merchant telecom rectifiers
  • Solar inverters and industrial motor drives
  • Uninterruptible power supplies
