February 2009 SP6682 High Efficiency White LED Charge Pump Regulator Rev. 2.0.0 GENERAL DESCRIPTION The SP6682 is a current regulated charge pump ideal for converting a Li-Ion battery input for driving white LEDs used in backlighting color displays or cell phone camera flash applications. The charge pump automatically switches between x1.5 and x2 modes based on the program-mable VMODE voltage, providing improved efficiency over traditional methods using charge pump doubler followed by LDO. This input voltage threshold can be externally programmed by a resistor divider network for optimized efficiency at specific output voltages and currents. The SP6682 operates with an internal 600kHz clock, which reduces switching noise and improves VOUT ripple.
