The STLED524 is a 5x24 LED dot matrix display driver. It includes 24 low-side current mirrors (for each LED in a row). Rows are multiplexed by 5 internal PMOS transistors.Current mirrors are supplied by the integrated boost converter. Its output voltage is adjustable so it can be adapted to the forward voltage of LEDs. It reduces power dissipation and improves efficiency.
