FT886A-RT

Overview

The FT886A-RT is an AC/DC offline switcher LED driver IC manufactured by Fremont Micro Devices Ltd. It features a step-down (buck) topology with an internal switch, designed for single-output applications delivering up to 180mA. The device operates within a supply voltage range of 9.6V to 25V and supports dimming functionality. Packaged in an 8-SOP surface-mount case, it functions across a temperature range of -40°C to 125°C.

Feature Summary

• Integrates an internal high-voltage switch for compact offline power conversion
• Supports dimming control for adjustable LED brightness
• Utilizes step-down buck topology for efficient energy transfer

Applications

• LED backlighting systems
• General illumination lighting fixtures

Procurement Notes

Verify the specific suffix '-RT' corresponds to the required tape-and-reel packaging configuration. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the 8-SOP footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buck converter is required for low-current LED loads. The integrated switch simplifies bill of materials compared to discrete solutions. Verify that the input voltage profile remains within the specified 9.6V to 25V operational window for stable performance.

Part Context

This part belongs to the FT886 family of offline LED drivers from Fremont Micro Devices. It shares architectural similarities with other members like the FT8260 series but is optimized for specific current and voltage requirements typical in backlight and general lighting applications.

Replacement Considerations

The FT8260-RT is listed as a similar alternative by distributors. Verify pin compatibility and electrical specifications before substitution.
