August 2009 SP6686 400mA Buck/Boost Charge Pump LED Driver Rev. 2.0.0 GENERAL DESCRIPTION The SP6686 is a current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The SP6686 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. A low current sense reference voltage (50mV) allows the use of small 0.
