Power Supply
2.10 Power Supply
The main power input, 12V DC at 4.0A, to the DSP56F807EVM is through a 2.1mm coax
power jack. A 4.0A power supply is provided with the DSP56F807EVM; however, less
than 500mA 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
DSP56F807EVM provides +3.3V DC voltage regulation for the DSP, memory, D/A,
CAN, parallel JTAG interface and supporting logic; refer to
Figure
2-8. Power applied to
the DSP56F807EVM is indicated with a Power-On LED, referenced as LED10.
