3 Test Setup

Table 3-1 shows the typical parameters for LP5890EVM.

Table 3-1 LP5890EVM Parameters
ParameterValue
VCC Device supply voltage2.5–5.5 V
VLEDR/G/B supply voltage2.5–5.5 V
ICH Constant output source current0.2–20 mA
The LP5890EVM can work with the MSP430F5529 LaunchPad.

The LP5890EVM 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.
