System Power Requirements
Table 21
provides the DC power supply design criteria.
NOTES:
1. V_DC is set for 12.0V in order to determine typical V_DC current.
2. V_DC is set for 7.5V in order to determine maximum V_DC current.
3. A 20-
μ
S duration.
4. This is V_DC dependent. See
Figure 7
for data of IDC-RMS vs. V_DC.
5. These values are system dependent.
6. Specifications labeled N/A are not applicable.

Processor Core Voltage Regulation
The DC voltage regulator (DC/DC converter) is designed to support the core voltage and I/O ring
voltage for current and future Intel mobile processors. The DC voltage regulator provides the
appropriate mobile Celeron processor core voltage, the GTL+ bus termination voltage, the
processor sideband signal pull-up voltage, and the clock driver buffer voltage. Of these voltages,
only the processor sideband pullup voltage (V_CPUPU) and the clock driver buffer voltage
(V_CLK) are delivered to the system electronics.
The mobile module supports input DC voltage range of 7.5V ~ 21.0V from the system battery or
power supply for mobile applications.
5.3.1
Voltage Regulator Efficiency
There are three voltage regulators on the mobile module. These voltage regulators generate the
core voltage used by the CPU and the voltage for the CPU I/O ring voltage. The core voltage
regulator provides the required current from the V_DC supply and its relative efficiencies are
shown in
Table 22
and
Figure 5
. The V_CLK and Vtt voltage regulators tap the V_3 plane.
