The STEVAL-TLL010V1 demonstration board is based on the STLA02, a 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 VOUTand FB pins. The STLA02 device contains high-side sensing to simplify the PCB layout in terms of LED connection.
The output current is dimmable by the PWM signal applied to the EN pin with minimum PWM frequency equal 100 Hz.
