- General illumination
Procurement Notes
Verify the obsolete status of the FT833A11-RT before procurement planning. Confirm availability through authorized distributors or secondary markets. Check for tariff implications if shipping to the United States. Ensure compatibility with existing 8-SOP footprints and thermal management requirements for the specified operating temperature range.
Selection Notes
Select this component for applications requiring primary-side regulation without optocouplers. Consider the fixed 420mA output current and 8-SOP package constraints. Evaluate the wide input voltage range suitability for global AC mains operation. Verify that the non-dimmable nature aligns with system requirements.
Part Context
This part belongs to the FT833xxx series from Fremont Micro Devices, which focuses on high-efficiency power management solutions. The series is characterized by primary-side regulation techniques that eliminate secondary feedback components. Fremont Micro Devices specializes in non-volatile memory and power ICs, establishing itself as a provider of energy-efficient semiconductor designs.
Replacement Considerations
The FT833A11-RT is marked as no longer manufactured. Identify equivalent primary-side regulated LED drivers with similar 420mA output and 8-SOP packaging. Verify pinout compatibility and electrical specifications such as input voltage range and operating temperature limits when selecting substitutes.
