System Power Requirements
Table 22
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 8
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 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 an input DC voltage range of 7.5V ~ 21.0V from the system battery or
power supply.
