Texas Instruments LMG2100EVM-078 Evaluation Module
Texas Instruments LMG2100EVM-078 Evaluation Module is designed to evaluate the LMG2100 half-bridge power module with two 100V, 4.4mΩ GaN FETs driven by an 80V GaN FET half-bridge gate driver. The board is a compact, easy-to-use power stage with an external PWM signal. It can be configured as a buck converter, boost converter, or other converter topology using a half-bridge. Because this is an open-loop board with an external PWM signal, it is not used to evaluate transient response.
The TI LMG2100EVM-078 evaluation module demonstrates the performance of the LMG2100 as a hard-switched converter to sample measurements such as efficiency, switching speed, and dv/dt (slew rate). The module can supply up to 20A of current if the application includes adequate thermal management (monitor case temperature and verify adequate airflow is present if required). The thermal management references include forced air, heat sink, and lower operating frequency to minimize the power dissipation in the module.
