Texas Instruments LMG5200 | Demoboard LMG5200POLEVM-10

Description

The LMG5200 evaluation module is a small, easy-to-use power stage with an external PWM signal. Theboard can be configured as a buck converter, boost converter or other converter topology using a halfbridge. Because this is an open loop board with an external PWM signal, do not use it to evaluatetransient response. It can be used to evaluate the performance of the LMG5200 as a hard-switchedconverter to sample measurements such as efficiency, switching speed and dv/dt. The EVM features aLMG5200 half-bridge power module with two 18-mΩ GaN FETs and a half-bridge driver. The module candeliver up to 10 A of current if the application includes adequate thermal management (monitor casetemperature and ensure adequate airflow is present if required). The thermal management considerationsinclude forced air, heat sink and lower operating frequency in order to minimize the power dissipation inthe module.

Features
