How to adjust output current according to LED temperature and binning of a DC-DC LED driver?

Our LITIX boost controllers like TLD5099EP have two options to dim the output current without a microcontroller:

  • Analog current adjustment
  • Embedded PWM engine

In the system these two options can be used to:

  • adjust the output current as a function of binning resistor 
  • thermal foldback (thermal protection)

The two functions are activated by analog voltages at the pins SET  and PWMI - e.g. by resistor dividers. Then are no interferences between these two functions.

See the datasheets at our LITIX pages
