Overview
The FT825-RT is a primary-side-control offline LED lighting controller manufactured by Fremont Micro Devices Ltd. It is designed to achieve high power factor and accurate LED current regulation for isolated lighting applications. The device operates within an AC supply voltage range of 85V to 265V and features an internal switcher. It supports dimming functionality and is housed in an 8-SOP (8-SOIC, 0.154" width) surface-mount package. The component is rated for an operating temperature range of -40°C to 125°C (TA).
Feature Summary
- Primary-side control architecture eliminates the need for secondary side feedback components.
- Integrated PFC capability ensures high power factor performance.
- Supports dimming functions for adjustable lighting output.
Applications
- Isolated LED lighting systems
- Offline AC/DC LED drivers
- General illumination fixtures
Procurement Notes
Verify the specific suffix 'RT' corresponds to the required tape-and-reel packaging configuration as indicated by distributor listings. Confirm that the 8-SOP package dimensions align with your PCB footprint requirements. Ensure the design accounts for the specified operating temperature range of -40°C to 125°C. Cross-reference the manufacturer part number FT825-RT with official datasheets to confirm active status and pinout compatibility before integration.
Selection Notes
Select this component for designs requiring primary-side regulation to reduce bill of materials cost by removing optocouplers. It is suitable for applications needing integrated PFC without complex secondary circuitry. Consider the 8-SOP package size for space-constrained layouts. Verify input voltage ranges match the target AC mains specifications. Ensure thermal management strategies support the 125°C junction temperature limit.
Part Context
The FT825-RT belongs to the FT825 series from Fremont Micro Devices, focusing on efficient offline LED driver solutions. This series targets the lighting market by simplifying isolated converter designs through primary-side control techniques. The manufacturer specializes in power management ICs and non-volatile memory products, establishing this controller as part of their broader portfolio for energy-efficient electronic lighting applications.
