The LMG2100 evaluation module is a compact, easy-to-use power stage with an external PWM signal. The board 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, do not use to evaluate transient response. The device can be used to evaluate the performance of the LMG2100 as a hard-switched converter to sample measurements such as efficiency, switching speed and dv/dt (slew rate). The EVM features a LMG2100 half-bridge power module with two 100 V, 4.4-mΩ GaN FETs driven by 80-V GaN FET half-bridge gate driver. The module can deliver up to 20 A of current if the application includes adequate thermal management (monitor case temperature and verify adequate airflow is present if required). The thermal management considerations include forced air, heat sink, and lower operating frequency to minimize the power dissipation in the module.
