Power Supply; Block Diagram Of The Power Supply - Motorola DSP56F801 Hardware User Manual

2.8 Power Supply

The main power input to the DSP56F801EVM, +12V DC at 4.0A, is through a 2.1mm
coax power jack. A 4.0A power supply is provided with the DSP56F801EVM; however,
less than 300mA is required by the EVM. The remaining current is available for user
motor control applications when connected to an optional motor power stage board. The
DSP56F801EVM provides +3.3V DC voltage regulation for the DSP, parallel JTAG
interface and supporting logic; refer to Figure 2-7. Power applied to the DSP56F801EVM
is indicated with a Power-On LED, referenced as LED8.
