CL6808 datasheet pinout

Description :

The CL6808 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 7V and 40V and provides an externally adjustable output current of up to 1.2A. Depending upon supply voltage and external components, this can provide up to 35 watts of output power. The CL6808 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
