LMG2100R026 Evaluation Module
Description
The LMG2100R026 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. The device can be used to
evaluate the performance of the LMG2100R026 as
a hard-switched converter to sample measurements
such as efficiency, switching speed and dv/dt (slew
rate). The EVM features a LMG2100R026 half-bridge
power module with two 100V, 2.6mΩ GaN FETs
driven by 90V GaN FET half-bridge gate driver.
The module can deliver up to 40A 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. Do not use to evaluate transient
response because this is an open-loop board with an
external PWM signal.
