LED Drivers -> SRAM Embedded S-PWM LED Driver
LED Drivers -> Multifunction LED Drivers (PrecisionDrive™ / Share-I-O™)
Share-I-O technology is characterized by pin compatibility. Thanks to the Share-I-O technique, it is possible to add additional functions to the LED drivers without adding more pins in the package and without modifying the circuit board originally designed for conventional LED drivers.

LED Drivers -> Driver generico a corrente costante
La serie di driver LED PrecisionDrive offre una precisione di corrente di ± 2,5% tra i canali di uscita di un singolo circuito integrato e di ± 3% tra i circuiti integrati.

LED Drivers -> S-PWM Driver
La tecnologia S-PWM (Scrambled-PWM) migliora la modulazione della larghezza di impulso, rimescolando l'immagine in diverse sotto-immagini con la stessa qualità di colore. Questo miglioramento aumenta in modo equivalente la velocità di aggiornamento dell'immagine. Quando si costruisce un display LED a 16 bit in scala di grigi, S-PWM evita gli sfarfallii e migliora la fedeltà.
