SP6683 Overview
The SP6683 is a high power current regulated charge pump ideal for converting a Li-Ion battery input for driving up to 8 white LED’s used in backlighting color displays. The SP6683 operates with an internal 1.2MHz clock, enabling the use of small external ponents. Output current can be accurately regulated by modulating the switcher between the charge pump and output capacitor.
