Chapter 6 Power Delivery Guidelines

This chapter provides the power consumption of SOM modules and the ATX/AT
power supply design recommendation for customer's reference.

6.1 SOM Power Consumption

The power consumption of each SOM module as below. Consider the power
consumption for different SOM module power requirement will be necessary.
Table 6.1 SOM series board Power Consumption
SOM Model CPU type
GX1 166MHz
4450 GX1 233MHz
GX1 300MHz
4451 SiS 200MHz
Celeron 400MHz
4470 PIII 500MHz
PIII 700MHz
C3 300MHz
C3 400MHz
C3 667MHz

Celeron 400MHz
4475 Celeron 650MHz
PIII 933MHz
Notes:
1. Operate entirely from 5-volt input power.
2. To accommodate the fastest future modules, it is recommended that the 5V
supply be capable of delivering 6 amperes average current to the SOM-ETX
module (with momentary peak current to 9 amperes).
3. It is also recommended that the thermal management solution be capable
of removing 30 watts from the SOM-ETX module's heat spreader plate
while maintaining conservative operating temperatures.
