Beschreibung
Demonstration circuit 2176A features the LT®3909, a2-string × 50mA, 2MHz step-up LED driver with ±1.8%current matching.The LT3909 precisely regulates two LED strings for equalcurrent, supports LED dimming that reduces brightnessdown to a 1/40,000 ratio, protects against faults and alsoreports faults. The LT3909 consists of a step-up converterwith a fixed 2MHz switching frequency and current sourcesfor the LED strings.
