The current of the four channels is simply programmed from 20mA to 400mA with an external resistor. The current match between any channels is ±0.5% (typical). Its operating frequency can be adjusted from 0.1MHz to 1MHz.
The AL3065A can be dimmed by one of the following modes: direct PWM dimming, PWM-to-analog dimming, or DC-to-analog dimming.
Robust protection Features include cycle-by-cycle...
