Description

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 V

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.
