1 / 4 page Data brief For further information contact your local STMicroelectronics sales office. November 2011 Doc ID 018913 Rev 1 1/4 4 STEVAL-ILL039V2 Step-up current controller for 4 LEDs based on the STLDC08 driver Features ■ Input voltage: 0.8 V to 3.6 V ■ Output: 4 LEDs at ILED = 300 mA ■ Dimming mode with external PWM signal ■ RoHS compliant Description The purpose of the 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).
