7/ Features and Power Supply
7.1. Onboard Power Supply
The SKL-S/mITX implements an on-board Intel IMVP8 regulator for the processor core and graphics core power
supply. The main feature of Intel IMVP8 regulator is that it is serial Voltage Identification Definition (VID) based. Both
the processor core and graphics core Voltage Regulator (VRs) are integrated into a single package. The Serial VID
interface is shared by both the CPU core and graphics core VRs.
Intel IMVP8 uses a three-wire serial interface called Serial Voltage Identification (SVID) with DATA, CLK and ALERT#,
for regulating both the CPU core & Graphics core processor voltages.
Some of the main differences in the platform with the introduction of SVID are:
 SVID can be used to communicate the power states along with the VID signals. Hence signals like PSI# and
DPRSLPVR which were used to indicate the power states in previous platforms, is absent in this platform.
 There is no support for on-board override mechanism as done in case of Parallel VIDs in previous
platforms.
7.2. External Power Supply
The SKL-S/mITX will operate from standard ATX & BTX compliant power supplies. For example, the Sparkle Model
No. FSP300-60BTVS meets this requirement and is an ATX12V 1.1 Spec compliant power supply.
Only connect to a power supply delivering the specified input rating and complying with the
requirements of Safety Extra Low Voltage (SELV) and Limited Power Source (L.P.S.) of IEC
60950-1 and the Energy sources (ES1) of IEC 62368-1.
Use an “ATX12V” 1.1 Spec compliant power supply regardless of Vendor or wattage level (an
ATX12V" rating means 5 V min current =0.1A)
The ATX 12V specification does not clearly state a requirement for the ramp-up of the 5VSB
standby voltage. However, we strongly recommend to use only PSUs where the 5VSB ramp
up follows the same rules as listed for +5VDC.
This should ensure that the board behaves properly, in particular when powering up without
or with a weak/empty battery.
The power supply used must comply with the requirements of the IEC 60950-1 or
IEC 62368-1 standard or better. In the case of an unintentional temporary under voltage
interruption use a power supply with an adequate holdup-time (brownout) and ensure the
power supply has been fully tested to at least meet the minimum immunity of AC inputs
requirements, as stipulated in IEC 55024. Including power supplies marketed with a separate
AC/DC power converter.
