LD7860 12/30/2009 1A High-Brightness LED Driver with Integrated NMOS Switch REV：00 General Description The LD7860 is a controller for step-down converters, operating in continuous conduction mode and ideally for driving high brightness of power LEDs. The device operates with inputs from 6V to 30V and utilizes an external high-side current sense resistor to set the normal average output current of up to 1A. Depending on the selection of input voltage and external components, it can drive up to 7pcs of WLEDs (VF=3.5V). Output current can be adjusted below the set value, by applying an external analog or PWM control signal to DIM pin.
