FT822A-RT

Overview

The FT822A-RT is an AC/DC offline switcher LED driver IC manufactured by Fremont Micro Devices Ltd. It features a single output and operates within a supply voltage range of 85V to 265V. The component is housed in an 8-SOP surface-mount package with a width of 3.90mm. It supports dimming functionality and is rated for an operating temperature range of -40°C to 125°C (TA). The device is classified as obsolete.

Feature Summary

• Integrated AC/DC offline switching topology for direct mains connection
• Supports external dimming control interfaces
• Designed for high-temperature operation up to 125°C

Applications

• General lighting systems
• LED power supplies
• Offline AC/DC conversion circuits

Procurement Notes

Verify the obsolete status before procurement, as availability may be limited to existing stock or last-time buys. Confirm that the 8-SOP package dimensions match the target PCB footprint. Ensure the design accommodates the specified 85V to 265V input range and thermal requirements for the -40°C to 125°C operating environment.

Selection Notes

Select this component only if an obsolete part is acceptable for the design lifecycle. The single-output configuration limits flexibility for multi-channel LED arrays. Verify compatibility with the required dimming protocol. Consider alternative active components if long-term supply stability is critical for the product roadmap.
