Hardware Setup
After connecting the power supply between J1 and J2, turning on the power supply, and installing JP1 and
JP2, the EVM regulates the default current per
JP2, the EVM regulates the default current per
through the WLEDs. Additional input capacitance
may be required in order to mitigate the inductive voltage droop that occurs at start-up and/or during a
load transient event.
load transient event.
In order to implement analog dimming via a PWM signal, remove the jumper on JP1 and the 10-pin ribbon
cable from J5, if installed, and perform the following steps in any sequence:
cable from J5, if installed, and perform the following steps in any sequence:
•
Connect the power supply between J1 and J2 and turn on the power supply.
•
Make sure that JP2's jumper is installed.
•
Connect the appropriately configured function generator to the CTRL side of JP1.
The PWM signal's duty cycle is directly proportional to the regulated current.
To implement analog dimming by sending the digital control via a PC running the TPS6116x Controller
software and USB-TO-GPIO interface box, remove the jumper or the function generator on JP1, and
perform the following steps in any sequence:

perform the following steps in any sequence:
•
Connect one end of the USB-TO-GPIO box to the PC using the USB cable and the other end to J5 of
the TPS6116xEVM using the supplied 10-pin ribbon cable as shown in the following illustration. The
connectors on the ribbon cable are keyed to prevent incorrect installation.
