1.2 Considerations

  • Unless otherwise noted, the input voltage was set to 12V.
  • A fan was used to blow air across the board with a heat sink mounted on the GaN switches on the bottom side.
  • The 1250W peak output power test was done with 1kW base load and 250W dynamic load set to 2Hz, 20% duty cycle.
