Other Board Features
Test pin probe points are installed for Vbus, Vout, and GND for waveform and efficiency measurements. For
higher power loss situations, there is a 30x30mm² heat sink and fan assembly with thermal interface
material applied, which can be fastened to the back of the PCB using the integrated spring pin system.
Further information on operating conditions for safe handling of the EVB can be found in EVB Operation
Conditions.
Power Good indicators, which are individually labelled LEDs, signal the presence of power for the 5V supply
(to the IC), the 12V fan supply and Vbus. When the LED illuminates, voltage is present on the corresponding
supply.
Board Block Diagram
The EVB layout has been simplified to a block diagram in Figure 3 to demonstrate the primary electrical
connections on the board, centered around the functionality of the MDC901 GaN gate driver.
