DESCRIPTION

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 components.

Output current can be accurately regulated by modulating the switcher between the charge

pump and output capacitor. In shutdown mode, the SP6683 discharges the output to ground

and draws less than 500nA current. Offered in 10-pin DFN package, the SP6683 family

includes three options that allow the user to optimize LED driving circuit; SP6683-LV with low

voltage reference, SP6683-03 with high impedance output in shutdown, and SP6683 with

pulled down output in shutdown.
