2.1 Hardware Setup

In the default jumper setting, the board can be evaluated by USB power directly and does not need an external power supply. Setup connection is demonstrated in Figure 2-1. The setup procedure is as follows:

  1. Connect the USB2ANY with the LP5861TEVM using the 30-pin ribbon cable.
  2. Plug the USB cable into the USB port on the computer.

Figure 2-2 shows the default jumper settings.

If maximum current is set above 20 mA, then an external VLED supply is recommended during evaluation since the USB can only provide around 400-mA current. The setup procedure is as follows:

  1. Connect the USB2ANY to the LP5861TEVM using the 30-pin ribbon cable.
  2. Connect a 5-V external power supply to the VLED_EXT terminal (see Figure 2-3) and connect the switching jumper (J1) to another side.
  3. Plug the USB cable into the USB port on the computer.
