Bench Power Supplies Using Banana Jacks
Socketed fuses are provided to isolate the voltage planes from the
regulators to allow bench supplies to power these sections using banana
jacks. The bench supply inputs are placed after the other power supplies
(whether linear or switching supplies) on the Cyclone II DSP
development board in order to allow current draw measurements.
Figure 2–24 shows a block diagram of the power supply generation and
distribution.

Before you connect a bench power supply, remove fuses on the
Cyclone II DSP development board. All fuses are LITTLEFUSE
154 007 and are 7 A. The fuses do not protect the board from
power surges.
