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 1µA current. The SP6683 utilizes 1µF capacitors to deliver up to 200mA

current regulated WLED drive capability. The SP6683 is offered in 10-pin DFN or MSOP

package.
