Image 4: Supply voltage for system units
Description
15 V is generated from the supply voltage using a DC/DC converter. This electrically isolated 15 V supplies further
DC/DC converters, which generate the remaining voltage.
After the system is turned on (e.g. using the power button), the 3V3 and 5 V voltages are active on the system.
