Descripción
- STEVAL-TLL010V1, Demonstration Board using STLA02 boost converter dedicated to powering and controlling the current of white LEDs in an LCD backlight. The device operates at a typical constant switching frequency of 2.3 MHz. It steps an input voltage ranging from 2.5 V to 18 V, up to 27 V. The output current is adjustable by the resistor RFB connected between the VOUT and FB pins. The STLA02 device contains high-side sensing to simplify the PCB layout in terms of LED connection
