Texas Instruments LMG341xEVM-018 Daughter Cards

Texas Instruments LMG341xEVM-018 Daughter Cards configure two LMG3410R050 or two LMG3411R050 600V GaN FETs with integrated driver and protection, in a half-bridge. These evaluation modules come with all the necessary auxiliary peripheral circuitry. These evaluation modules are also designed to work in conjunction with larger systems.

Features

Two options to bias the LMG341x, isolated power or from bootstrap diode
Over temperature, overcurrent, and under-voltage lockout protection with FAULT indication that is level shifted to an AGND referenced signal

Gate logic input support of either 3.3V or 5V logic
The maximum recommended operating voltage of 480V and the absolute maximum voltage of 600V

Applications

The LMG341xEVM-018 is designed for use in AC/DC, DC/DC and DC/AC applications
- Totem-Pole PFC converters
- Phase-Shifted Full Bridge or LLC Converter
- Buck converter such as the LMG34XX-BB-EVM

Required Equipment

DC Voltage Source – capable of supplying the input of the evaluation module up to 480V
DC Bias Source – capable of 12V output at up to 0.7A
Function Generator – capable of 0V to 5V square wave output with adjustable duty cycle and frequency in the desired operating range
- It is recommended to operate the LMG341xEVM-018 with a switching frequency between 50kHz to 200kHz

Oscilloscope – capable of at least 200MHz operation
- A 1GHz or greater oscilloscope and probes with short ground springs are recommended for accurate measurements
DC Multimeter(s) – capable of 600V measurement, suitable for determining operation and efficiency (if desired)
DC Load – capable of 600V operation at up to 8A in current-mode operation
Fan – 200 LFM minimum airflow is recommended
