LT3466 is a dual-output full-featured step-up DC / DC converter. The two LED strings can be dimming by each CTRL pin independent control, and the internal PWM dimming system can provide PWM signal for their respective PWM pin, thus dimming range is extended to 1000:1. The LT3486's operating frequency can be set by external resistors, and their range is 200kHz ~ 2MHz. The current detection circuit has the low feedback voltage (200mV) to reduce power consumption of the current-sense resistor and improve the efficiency of the circuit, and it has LED open circuit output voltage limiter function.
