LMG2100EVM-078 Evaluation Module
Description
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.
