WLEDEVM-260 WLED Load Board
The WLEDEVM-260 load board contains 8 white light emitting diode (WLED) banks/strings which contain
either 10 or 12 WLEDs as selected by the odd numbered jumpers (JP1, JP3, etc.). The even numbered
jumpers (JP2, JP4, etc.) can be used to insert a current meter, or to remove the WLEDs from the circuit.
The test points (TP1-TP89) can be used to measure the voltage drops between WLEDs and/or short out
WLEDs. J1 connects to the 14-pin ribbon cable provided. The TPS6118xEVMs have the matching header
for the ribbon cable, and thus can be used to power the WLEDs.

This EVM has several white LEDs that shine very bright. Protective
eye wear and/or the provided dark plastic diffuser to cover the
white LEDs is recommended.
