SP6683ER-L/TR

Overview

The SP6683ER-L/TR is a high-power current-regulated charge pump LED driver designed for converting Li-Ion battery input to drive up to eight white LEDs. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a regulated output current of 200 mA. The device supports PWM dimming and functions in a switched-capacitor topology. It is housed in a 10-DFN (3x3 mm) package, suitable for surface-mount installation. The component operates between -40°C and +85°C with a maximum power dissipation of 1.2 W.

Feature Summary

• High-efficiency charge pump topology for driving multiple white LEDs from a single-cell Li-Ion source
• Integrated pulse-width modulation (PWM) dimming capability for precise brightness control
• Current-regulated output ensuring consistent LED performance across varying input conditions

Applications

• Mobile phone backlighting systems
• Camera flash lighting circuits
• Portable electronic device illumination

Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm availability through authorized distributors or secondary markets as standard supply chains may not stock this discontinued part. Ensure compatibility with existing PCB footprints if replacing earlier revisions. Check RoHS compliance documentation for specific manufacturing lot requirements.

Selection Notes

Select this driver when designing compact LED backlighting solutions requiring high efficiency from a single-cell lithium-ion battery. The integrated charge pump eliminates the need for external inductors, reducing board space. Consider the 200 mA output limit and support for up to eight series-connected LEDs when sizing the optical load. Verify thermal management capabilities given the 1.2 W power dissipation rating in the small DFN package.

Part Context

This component belongs to MaxLinear's SP6683 series of high-power LED drivers. It is specifically engineered for portable applications where space constraints and battery efficiency are critical. The series utilizes CMOS technology to provide low-cost, high-performance solutions for mobile communication devices and consumer electronics requiring reliable white LED illumination.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product status is listed as obsolete, engineers must evaluate alternative LED driver ICs from other manufacturers that offer similar charge pump topologies, 200 mA output current, and compatible 10-DFN packaging.
