SP6683 White LEDs Driver for Parallel Configuration Copyright 2004 Sipex Corporation
SP6683
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 1
μ
A current. The SP6683 utilizes 1
μ
F capacitors to deliver up to 200mA
current regulated WLED drive capability. The SP6683 is offered in 10-pin DFN or MSOP
package.
