Description

  • STEVAL-ILL039V2, Demonstration Board is to provide an example for applications of an LED driver using the step-up controller STLDC08. The STLDC08 is designed for handheld equipment supplied by AA or AAA batteries and provides a precise constant current starting from a variable input voltage source. The LED current is set by an external sense resistor inserted between the feedback pin (FB) and GND. A regulation loop holds the voltage drop at the sense resistor at a constant level (typ. 100 mV)

Key Features

  • Input Voltage
    0.8 to 3.6 V
  • Output Current
    0.3 A
  • Number of Derived Elements
    4
