www.ti.com Hardware Overview
The Resonant Converter EVM board is intended to be a learning tool – not a turn-key solution. It
demonstrates the functionality of a larger systems at a safe input voltage and power level. It is not
intended to demonstrate any extreme in electrical design (smallest size, highest efficiency). Since the
EVM board is a learning platform, it has a conservative board layout and multiple test points allowing the
user to easily probe the most significant waveforms. Figure 1 is a diagram of the EVM board and some
key features.
