Functional Description
1 Power Supplies
The Zybo Z7 power circuitry was carefully designed to meet the requirements of the Zynq-7000 and all other
peripherals while also providing flexible input supply options. An overview of the power circuit is shown in Fig. 1.1.
Figure 1.1. Power circuit overview
All on-board power supplies are enabled or disabled by the power switch (SW4). The power indicator LED (LD13,
labeled PGOOD) is on when all the supply rails reach their nominal voltage.
1.1 Power Input Sources
The Zybo Z7 can be powered from several different sources. Jumper JP6 (near the power switch) determines which
power source is used. There are three valid configurations for this jumper corresponding to the three powering
options: USB, wall wart supply with barrel jack, and battery pack. Figure 1.1 depicts all three, and a diagram on the
board silkscreen does as well.
