LYT6070C-TL

LED Driver IC Overview

The LYT6070C-TL is a high-power LED lighting driver IC from the LYTSwitch-6 series by Power Integrations. It integrates a multi-mode Quasi-Resonant (QR)/CCM flyback controller, an integrated PowiGaN high-voltage switch, secondary-side control, and a synchronous rectification driver into a single InSOP-24D package. The device supports an input voltage range of 85 VAC to 305 VAC and delivers up to 85 W of output power. It features a fixed operating frequency of 25 kHz and can handle a maximum output current of 10 A. The component operates within a temperature range of -40°C to +150°C.

LED Driver IC Feature Summary

• Integrates primary and secondary controllers with a HIPOT-isolated FluxLink feedback mechanism for precise constant current regulation independent of transformer design.
• Utilizes PowiGaN technology to achieve high efficiency across the full load range without requiring external heat sinks.
• Includes comprehensive protection features such as automatic restart input overvoltage protection and thermal foldback.

LED Driver IC Applications

• Isolated off-line LED drivers
• Smart LED lighting systems
• High-voltage flyback post-regulation circuits

LED Driver IC Procurement Notes

Verify the specific suffix TL indicates tape and reel packaging when sourcing components. Confirm that the part number matches the exact power rating and package type required for the design. Ensure compliance with RoHS standards and check for any regional distribution restrictions before finalizing procurement plans.

LED Driver IC Selection Notes

Select this component for designs requiring high power density and simplified bill of materials due to its high integration level. The integrated FluxLink technology eliminates the need for optocouplers and auxiliary windings. Consider the thermal performance characteristics when designing enclosures to ensure reliable operation under varying ambient conditions.
