LYT3314D-TL

LED Driver IC Overview

The LYT3314D-TL is a single-stage LED driver IC from the LYTSwitch-3 family, designed for high-performance lighting applications. It integrates a 650V power switch and supports primary-side regulation with constant current output. The device features built-in power factor correction (PFC) and operates within an input voltage range of 85 VAC to 265 VAC. It delivers up to 5.7 W of output power and is housed in a SO-16B-14 package. The component includes comprehensive protection mechanisms such as over-voltage, over-current, and thermal shutdown.

LED Driver IC Feature Summary

• Integrates a 650V power switch with primary-side regulation for simplified design
• Provides built-in power factor correction and constant current control
• Supports triac dimming compatibility for adjustable lighting systems

LED Driver IC Applications

• General illumination LED bulbs
• LED downlights and spotlights
• Commercial linear lighting fixtures

LED Driver IC Procurement Notes

Verify the specific suffix TL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the full part number against distributor catalogs to avoid confusion with non-tape variants.

LED Driver IC Selection Notes

Select this component for designs requiring integrated PFC and primary-side regulation without optocouplers. Evaluate thermal performance requirements based on the 5.7 W power limit. Consider the SO-16B-14 footprint constraints during PCB layout. Verify compatibility with target dimmer types if adjustable lighting functionality is required.

LED Driver IC Part Context

This part belongs to the LYTSwitch-3 series, which represents an evolution in integrated offline switcher technology. The series focuses on reducing external component count while maintaining high efficiency. The LYT3314D-TL specifically targets low-to-medium power LED applications where size and cost efficiency are critical design parameters.

LED Driver IC Replacement Considerations

LYT3316D-TL offers higher power capability within the same package. LYT3318D-TL provides increased output capacity for demanding applications. LYT3315D-TL serves as an intermediate power option in the series.
