Power Supply; Schematic Diagram Of The Power Supply - Motorola DSP56F826EVM Hardware User Manual

2.11 Power Supply

The main power input, +12.0V DC, to the 56F826EVM is through a 2.1mm coax power
jack. An optional +5.0V DC power supply input is available through a 2-pin terminal
block, TB1. A 1.2A power supply is provided with the 56F826EVM; however, less than
500mA is required by the EVM. The remaining current is available for the user's custom
daughter card application, when connected to the daughter card interface. The power
regulation on the 56F826EVM provides +5.0V DC voltage regulation for the codec's
analog circuits and to the additonal voltage regulation logic on the EVM. The additional
voltage regulation logic provides +2.5V DC voltage regulation for the hybrid controller's
core and +3.3V DC voltage regulation for the controller's I/O, memory, parallel JTAG
interface and supporting logic; refer to
indicated with a Power-On LED, referenced as LED7.
