2.2 Test Setup

Table 2-4 shows the typical parameters for LP5891EVM.

Table 2-4 LP5891EVM Parameters
Parameter Value
VCC Device supply voltage 2.5–5.5 V
VLEDR/G/B supply voltage 2.5–5.5 V
ICH Constant output source current 0.2–20 mA
The LP5891EVM can work with the TMS320F280039C LaunchPad.

The LP5891EVM is designed to work in two different modes:

  • Single device
  • Multiple cascaded devices in independent mode

For simplicity, the test setup for single device and dual devices are illustrated.
