The LMG342X-BB-EVM is an easy-to-use breakout board to configure any LMG342xR0x0 half-bridge boards, such as the LMG3422EVM-043, as a synchronous buck converter. By providing a power stage, bias power and logic circuitry, this evaluation module (EVM) allows for quick measurements of the gallium nitride (GaN) device switching. This EVM is capable of delivering up to 12A of output current with adequate thermal management (forced air, low frequency operation, etc) to ensure the maximum operating temperature is not exceeded. This EVM is not suitable for transient measurements since it is an open loop board.
Only a single pulse width modulated input is required, with complementary pulse width modulated signals and corresponding dead time generated on board. Probe points are provided to allow for key logic and power stage waveforms to be measured with oscilloscope probes that have short ground springs.
