FT8260-RT

Overview

The FT8260-RT is an AC/DC offline switcher LED driver IC manufactured by Fremont Micro Devices Ltd. It features a single output and includes an internal power switch, eliminating the need for external switching components. The device operates within a supply voltage range of 9.6V to 25V and is housed in a compact SOT-23-6 surface-mount package. Designed for lighting applications, it supports dimming functionality and offers high current accuracy of ±3%. The component is rated for an operating temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Primary side control architecture that eliminates the requirement for secondary feedback circuits
• Single-stage active PFC implementation for achieving high power factor and low total harmonic distortion
• Integrated internal power switch for simplified circuit design

Applications

• General LED lighting systems
• Offline AC/DC power conversion for illumination
• Compact lighting fixtures requiring primary-side regulation

Procurement Notes

Verify the specific suffix 'RT' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the application environment remains within the specified -40°C to 125°C ambient temperature range to ensure reliable operation. Ensure input voltage conditions do not exceed the maximum 25V rating. Check for any regional compliance requirements regarding RoHS3 and REACH status before finalizing procurement.

Selection Notes

Select this component for designs prioritizing cost-effective primary-side regulation without optocouplers. It is suitable for applications requiring high power factor correction and low THD. The SOT-23-6 package is ideal for space-constrained PCB layouts. Consider the ±3% current accuracy specification for precision lighting needs. Evaluate thermal management strategies given the wide operating temperature range.

Part Context

This part belongs to the FT8260 family of isolated LED drivers from Fremont Micro Devices. The FT8260 series is engineered for efficient AC/DC conversion in lighting applications. The FT8260-RT variant specifically denotes the reel-packaged version of the standard FT8260 chip. These devices are designed to replace traditional multi-component solutions with a single integrated switcher.

Replacement Considerations

Consult official manufacturer documentation for qualified substitute part numbers. Verify pin compatibility and electrical specifications before substituting. Generic equivalents may lack the specific primary-side control or PFC characteristics of the original component.
