Leading-edge LED drivers have debuted featuring the harmonization of our proven technologies used in LVDS and power management ICs. THine's LVDS interface know-how makes them tolerant to surge noise and is expected to reduce data transmission errors drastically in electrically noisy environments, and LVDS repeater function can enables the LED drivers to be easily cascaded without the external buffers and the engineers' effort. The LED drivers also have the self-protection features utilized in our power IC products.
