This data brief provides detailed information on the STEVAL-ILL039V1 demonstration board, which is a step-up current controller for 2 LEDs based on the STLDC08 driver. It features an input voltage of 0.8 V to 3.6 V, an output of 2 LEDs at 200 mA, a dimming mode with external PWM signal and is RoHS compliant.
The document details the STEVAL-ILL039V1 demonstration board, which serves as an example application for the STLDC08 LED driver. The board is designed to provide precise constant current output for two LEDs using a step-up controller suitable for handheld equipment powered by AA or AAA batteries.
Key features include an input voltage range of 0.8 V to 3.6 V and a regulated output current (ILED) of 200 mA. The design supports dimming via an external PWM signal, with the LED current set by an external sense resistor connected between the feedback pin and ground.
| Input voltage range | 0.8 V to 3.6 V |
|---|---|
| Output configuration | 2 LEDs at ILED = 200 mA |
| Dimming mode | External PWM signal |
The device accepts an input voltage ranging from 0.8 V to 3.6 V.
It drives 2 LEDs at a current of 200 mA.
The current is set by an external sense resistor inserted between the feedback pin and GND.
