Overview
The FT8901B-RT is an AC/DC offline switcher IC designed for LED driver applications, manufactured by Fremont Micro Devices Ltd. It features an internal switch and provides a single output channel capable of delivering up to 700mA. The device operates within a supply voltage range of 7V to 27V and functions at a frequency of 45kHz. It is housed in an 8-SOP package with a width of 3.90mm. The component supports dimming capabilities and is rated for an operating temperature range of -40°C to +85°C. This product is currently classified as obsolete.
Feature Summary
- Integrated AC/DC offline switching capability for direct mains connection
- Built-in internal power switch eliminates external components
- Supports LED dimming functionality for brightness control
Applications
- LED lighting systems requiring offline AC/DC conversion
- General illumination drivers utilizing single-channel output
- Compact lighting fixtures compatible with SOP-8 packaging
Procurement Notes
Verify availability status carefully as this component is listed as obsolete. Confirm the specific suffix RT indicates tape and reel packaging if required for automated assembly. Cross-reference with the manufacturer or authorized distributors for final disposition and potential end-of-life management strategies before integrating into new designs.
Selection Notes
Select this component only if the design accommodates an obsolete part lifecycle. Ensure the application requires a 700mA output current and fits within the 7V to 27V supply range. Verify that the 8-SOP package dimensions align with the PCB footprint constraints. Consider alternative modern equivalents if long-term supply stability is critical for the product roadmap.
Part Context
The FT8901B-RT belongs to the FT8901 family of LED drivers from Fremont Micro Devices Ltd. It shares core specifications with the FT8901-RT but utilizes an 8-SOP package instead of SOT-23-6. This family targets cost-effective, compact AC/DC LED driving solutions. The B variant specifically denotes the package style difference while maintaining identical electrical performance characteristics for offline switching applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, manual evaluation of pin-compatible or functionally equivalent modern LED driver ICs is necessary. Consult the manufacturer for recommended obsolescence alternatives.
