CHAMP-AV8 (VPX6-462) HARDWARE USER’S MANUAL CURTISS-WRIGHT
1-32 PROPRIETARY 826448 VERSION 5 MARCH 2015
POWER REQUIREMENTS
Notes: 1. Power consumption (Watts) will vary depending on processor frequency, application
usage, and ambient temperature.
2. ±12VAux for XMC only (not used by CHAMP-AV8 basecard).
3. Vs3 (+5.0 VDC) is not used by the CHAMP-AV8.
4. VBAT is optional. VBAT sources current only when the board is shutdown or main power
is “off”. When the CPU is running, VBAT current is 0 Amps.
Power Supply
Requirements
• Base-board +12V P/S requirement (no XMC), typical current draw is less than 12A.
• Base-board AUX +3.3V P/S requirement, typical current draw is less than 0.3A.
Overall Thermal
Power Dissipation
• Thermal power dissipation (no XMC), typical dissipation is less than 135W.
