STEVAL-TLL013V1

5-channel (2 LEDs in series per channel) step-up white LED driver demonstration board based on the STLED25
  • active 活性

The STEVAL-TLL013V1 demonstration board was designed to demonstrate the performance of the STLED25, a fixed frequency, high-efficiency, boost DC-DC converter with five parallel high-side current sources.

The STLED25 is able to provide 125 mA of total current with a maximum voltage of 7.5 V on each channel.

Each current source supports single or dual LED connections. The output voltage of the step-up converter is automatically set at 100 mV above the highest voltage required on any driver to guarantee the proper operation of the linear current sources. The device implements a self-test feature to detect any failure of the LEDs and to disable the related channel.

The failure status is reset as soon the IC is disabled. This mode of failure detection allows the device to continue operating driver channels that are operating normally, while avoiding excessive power consumption or associated thermal issues.
