LM3509, High Efficiency Boost
The LM3509 current mode boost converter offers two separate outputs.
The first output (MAIN) is a constant current sink for driving series white LED’s.
The second output (SUB/FB) is configurable as a constant current sink for series white LED bias, or as a feedback pin to set a constant output volta
