By paralleling outputs, higher LED currents can be achieved. In addition, linear dimming in 3 discrete steps may be obtained
by enabling 1, 2, or 3 outputs.

CL325 power dissipation may be lowered by supplying the CL325 from a voltage source (VIN) that is lower in voltage than
the LED supply (VLL).
