CHIPLINK CL6808
The CL6808 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LE Ds efficiently from a voltage s ource higher than the LED voltage. The device operates from an i nput supply betw een 7V an d 40V and p rovides an extern ally adjustable output current of up to 1.2 A. 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.| Part No. | CL6808 |

GENERAL DESCRIPTION
Depending upon supply voltage and external components, this can provide up to 35 watts of output power. Output current can be adjusted above, or below the set value, by applying an external control signal to the 'ADJ' pin. The ADJ pin will accept either a DC voltage or a PWM waveform. Depending upon the control frequency, this will provide either a continuous or a gated output current. The PWM filter components are contained within the chip. The PWM filter provides a soft-start feature by controlling the rise of input/output current. The soft-start time can be increased using an external capacitor from the ADJ pin to ground. Applying a voltage of 0.5V or lower to the ADJ pin turns the output off and switches the device into a low current standby state.FEATURES
