LDS8620-002-T2

Overview

The LDS8620-002-T2 is a dual-output LED driver IC from the PowerLite series, manufactured by IXYS Integrated Circuits Division. It utilizes a switched capacitor (charge pump) topology to regulate current for LED applications. The device supports PWM dimming and delivers up to 96mA per channel. It operates within a supply voltage range of 2.7V to 5.5V, with output voltages reaching up to 6V. The component is housed in a 16-TQFN (3x3) surface-mount package with an exposed pad. It functions as a DC-DC regulator suitable for camera flash and other lighting applications.

Feature Summary

• Dual-output architecture providing independent regulation for two LED channels
• Switched capacitor charge pump topology for efficient DC-DC conversion
• Supports Pulse Width Modulation (PWM) dimming for brightness control

Applications

• Camera flash systems
• Portable device illumination
• LED backlighting circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm that the specific suffix -002-T2 matches the required 96mA output specification and 16-TQFN packaging. Check RoHS compliance status and ensure the part meets environmental regulations for your target market. Review datasheet revisions for any updates regarding electrical characteristics or recommended operating conditions before integration into final designs.

Selection Notes

Select this component when a compact, dual-channel LED driver with charge pump topology is required. Ensure the input voltage range aligns with the system's power supply capabilities. Consider the thermal performance of the 16-TQFN package for heat dissipation needs. Verify that the 96mA per channel output current meets the LED forward current requirements. Compare against alternative drivers if higher current or different topologies are necessary for the specific application constraints.

Part Context

The LDS8620-002-T2 belongs to the PowerLite family of LED drivers from IXYS. This series focuses on integrated solutions for portable electronics. Similar parts in the lineup may offer different output currents or configurations. The component is designed for space-constrained applications requiring efficient LED driving.
