• Utilizes FluxLink feedback technology to bridge the isolation barrier without requiring optocouplers.
• Provides precise constant current and constant voltage regulation independent of transformer design variations.

LED Driver IC Applications

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

LED Driver IC Procurement Notes

Verify the specific suffix 'TL' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the InSOP-24D package dimensions align with the target PCB layout constraints. Ensure the selected variant meets all necessary regional safety certifications such as UL1577 or TUV standards for the intended market deployment.

LED Driver IC Selection Notes

Select this component for designs requiring high efficiency across the entire load range without external optocouplers. It is suitable for applications demanding compact form factors due to its highly integrated architecture. Consider the thermal management requirements associated with the InSOP-24D package when designing for maximum power outputs near the 55 W limit.

LED Driver IC Part Context

This part belongs to the LYTSwitch-6 family, which focuses on simplifying offline LED driver development through extreme integration. The series eliminates the need for separate secondary controllers and feedback components, reducing bill-of-materials count and improving reliability compared to traditional multi-chip solutions.
