DESCRIPTION

The SP6682 is a current regulated charge pump ideal for converting a Li-Ion battery input for

driving white LED used in backlighting color displays. The charge pump automatically switches

between X1.5 and X2 modes based on the input voltage, providing improved efficiency over

traditional methods using charge pump doubler followed by LDO. This input voltage threshold

can be externally programmed for optimized efficiency at specific output voltages and currents.

The SP6682 operates with an internal 600kHz clock, enabling the use of small external

components. Output current or voltage can be accurately regulated by modulating the switcher

between the charge pump and output capacitor. In shutdown mode, the IC disconnects the output

from the input and draws less than 1.5碌A(chǔ) current. The SP6682 is offered in a 10-pin MSOP

package, and a small 10-Pin DFN Package.
