Processor Core Voltage
Regulation
The Intel Mobile Module supports an input DC
voltage range of 5V - 20V (+5 percent) slew-rate
controlled from the system battery/power supply.
Maximum peak input voltage is 21.1V including
ripple.
The
Intel Mobile Module’s DC voltage regulator
(DC/DC converter) is designed to support the CPU
core voltage and the 2.5V-only CPU interface
signals so no special voltage regulation is required
on the system electronics. The CPU interface
signals between the CPU and PIIX4 South Bridge
require proper termination to the V_CPUIO (2.5V)
power plane and should be treated with special
attention. Please refer to the signal definitions for
recommended resistor termination values.
3.4.1.
VOLTAGE REGULATOR
EFFICIENCY
The voltage regulator is optimized for Pentium
Processors and is most efficient in the 1A to 3A
range. When placed in suspend mode, the module
will consume approximately 20mW. See Table 12a
and 12b for details over the entire current range.

NOTES:
1.
The above measured efficiencies are typical values from a limited sample size. Results may vary across
different modules.
These efficiencies will change with future voltage regulators that accommodate higher input voltages.
