Overview
The FT8901-RT is an AC/DC offline switcher LED driver IC manufactured by Fremont Micro Devices Ltd. It provides a single output channel with a current rating of 700mA. The device operates within a supply voltage range of 7V to 27V and functions at a frequency of 45kHz. It features an internal switch and is housed in a SOT-23-6 surface-mount package. The component supports dimming capabilities and is rated for an operating temperature range of -40°C to 85°C (TA). This part is currently obsolete.
Feature Summary
- Integrated AC/DC offline switching topology with internal power switch
- Supports LED dimming functionality
- Compact SOT-23-6 surface-mount packaging
Applications
- LED lighting systems requiring offline AC/DC conversion
- General illumination applications using single-channel LED drivers
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct production lines. Confirm the specific suffix variant matches design requirements, as functional differences may exist between packaging options. Ensure compatibility with existing board layouts due to the SOT-23-6 footprint.
Selection Notes
Select this component only if the design accommodates an obsolete part status. Verify that the 700mA output current and 45kHz switching frequency align with thermal and electromagnetic interference constraints. The SOT-23-6 package limits power dissipation compared to larger packages. Confirm that the 7V to 27V input range suits the specific AC/DC converter topology being implemented.
Part Context
The FT8901-RT belongs to the FT8901 series of PMIC LED drivers from Fremont Micro Devices Ltd. It is designed for cost-effective, low-power LED applications where compact size is prioritized. The 'RT' suffix typically denotes tape-and-reel packaging. As an offline switcher, it integrates control logic and power stages into a single small-form-factor solution.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, alternative components must be evaluated based on pin compatibility, electrical specifications, and package dimensions.
