LYT0006D

LED Driver IC Overview

The LYT0006D is an offline LED lighting driver IC from the LYTSwitch-0 series by Power Integrations. It integrates a 700 V power MOSFET, oscillator, open-loop control, and protection circuits into a single SO-8C-7 package. Designed for universal input applications, it operates within an AC voltage range of 85 V to 308 V. The device delivers a maximum output current of 280 mA in constant current mode or 175 mA in multi-drive constant mode. It supports buck, flyback, SEPIC, and boost topologies with a switching frequency of 66 kHz. Operating temperatures range from -40 °C to +150 °C.

LED Driver IC Feature Summary

• Integrates a 700 V power MOSFET with high-voltage startup circuitry to eliminate bias winding requirements.
• Features simple open-loop control architecture that reduces external component count and system cost.
• Includes automatic restart circuitry to safely limit output power during fault conditions such as short circuits or open loops.

LED Driver IC Applications

• Low-cost LED bulb replacements
• Universal input LED drivers
• Compact LED lighting modules

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., D vs TL) against official datasheets, as packaging formats differ between tubes and reels. Confirm availability status, as this model may be subject to end-of-life notices or limited stock constraints. Ensure the selected variant matches the required thermal performance and regulatory compliance standards for the target market.

LED Driver IC Selection Notes

Select this component for designs requiring minimal external parts and high integration in low-power LED applications. The LYTSwitch-0 series is optimized for cost-sensitive markets where board space is limited. Consider the 700 V rating for direct mains connection without additional isolation transformers. Evaluate thermal management needs given the high junction temperature capability up to 150 °C.

LED Driver IC Part Context

The LYT0006D belongs to the LYTSwitch-0 family, which focuses on simplifying LED driver design through high integration. This series targets the replacement of traditional incandescent bulbs with efficient LED alternatives. The device combines power switching and control logic to reduce bill-of-materials costs and assembly complexity compared to discrete solutions.

LED Driver IC Replacement Considerations

Check for updated revisions within the same series. Verify pin compatibility if substituting with other LYTSwitch-0 variants. Ensure thermal and electrical ratings match the original design requirements.
