LDS8640-008-T2

Overview

The LDS8640-008-T2 is a regulated LED driver IC from the PowerLite series, manufactured by IXYS Integrated Circuits Division. It functions as a DC-DC switcher utilizing a switched capacitor (charge pump) topology to drive two output channels with a maximum current of 200mA per channel. The device operates within a supply voltage range of 2.7V to 5.5V and delivers an output voltage up to 6V. It integrates internal switches and supports PWM dimming control at a switching frequency of 1MHz. Designed for camera flash applications, it is housed in a 16-TQFN (3x3mm) package with exposed pad.

Feature Summary

• Dual-channel output capability for simultaneous LED driving
• Integrated charge pump topology eliminates external inductors
• Supports PWM dimming for precise brightness control
• Compact surface-mount packaging for space-constrained designs

Applications

• Camera flash systems
• Mobile device illumination circuits
• Portable electronic lighting modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolescence status. Confirm RoHS3 compliance and REACH registration details prior to integration. Check for potential tariff implications if shipping to specific regions. Validate that the 16-TQFN footprint matches the target PCB design constraints.

Selection Notes

Select this component for applications requiring dual-channel LED regulation without inductive components. Ensure input voltage remains between 2.7V and 5.5V. Consider the 200mA per channel limit when sizing LEDs. Verify thermal management requirements for the 16-TQFN package under continuous operation conditions.
