1.6 Power Supply
The EVM operates from a 5V external power supply connected to the main
power input (J7), a 2.5 MM. barrel-type plug. Internally, the +5V input is converted
into +1.2 to 1.35V, +1.8V and +3.3V using Texas Instruments TPS65530 power
management IC and various linear regulators. The +1.2 to 1.35V supply is used for the
DSP core while the +3.3V supply is used for the DSP's I/O buffers and other chips on
the board. The +1.8 volt supply is used for DM365 DDR2 memory, and other on chip
peripherals.
