The STEVAL-TLL001V1 is a White LED Controller Evaluation board. It is a boost converter that operates from 3.0 V to 5.5 V and can provide an output voltage as 37 V and can drive up to 10 white LEDs in series.

The converter is a PFM (pulse frequency modulation) inductor switches and can work in discontinuous (DCM) mode operation. A minimum OFF time of the embedded boost switch TSW is fixed internally and allows limiting the switching frequency.


  • Inductor switches boost controller
  • PFM mode control
  • High efficiency over wide range of input voltage from 3.0 V to 5.5 V
  • Over-voltage protection with automatic restart
  • Adjustable peak current limit
  • Enable pin with possibility of PWM dimming control
  • Low shutdown current <1 μA
