2.2 Power
The power supply system of the T1040RDB board uses power from a standard ATX
power supply unit (PSU) to provide the required power supplies to the processor, CPLD,
and peripheral devices. In addition to meeting required power specifications, the
following goals guide the power supply architecture:
• Monolithic power supply for VCC that powers internal cores and platform logic
• T1040RDB can access IR36021 via software to check the current and voltage values
or to program the voltage changes
• All power supplies are sequenced per hardware specifications
The figure below shows an overview of the power supply.
