LED DRIVER IC HELP

[TC61]

Hello,

I was wondering if someone could take a look at this LED Driver I am working with and tell me how the Control Inputs are used. They look like simple on off inputs but I don't know if they are routed to ground to be on, or you need a voltage input to trigger the on off.

I attached the cut sheet with the diagram on it. The CTL 1, 2, 3 are what I am looking at.

Thanks in advance

Tim

It sounds like you aren't using them? If that's the case and you want all the LEDs ON then just tie all three of them to Vin. It's the truth table on page 6. Read 1 => Vin and 0 => to GND.
