4.1 Precaution and Wire Gauge
CAUTION:
For evaluation only, not FCC approved for resale
Prolonged operation with low input at full power will cause heating of the MOSFET, the diode, the
sense resistor and the inductor. It is recommended to use a fan with a minimum of 200LFM.
Board surface is hot. Do not touch. Contact may cause burns.
Wire gauge for the input power supply should be 8 AWG minimum, soldered to the EVM and no longer
than 1 foot each for VIN and GND. Wire gauge for the output electronic load should be 14 AWG minimum,
soldered to the EVM and no longer than 1 foot each for VOUT and GND.
