Overview
The FT883B-RT is an AC/DC offline switcher IC designed for LED driver applications. It supports step-down (buck) and step-up (boost) topologies with a single output. The device integrates internal switches and provides a constant current of 60mA. It is housed in an 8-SOP package.
Feature Summary
- Integrates internal power switches for simplified circuit design
- Supports both buck and boost converter topologies
- Provides constant current regulation for LED loads
Applications
- LED lighting systems
- Offline AC/DC conversion circuits
- Constant current LED drivers
Procurement Notes
Verify the specific suffix 'RT' corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the 8-SOP footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a single-output solution supporting both buck and boost operations is required. The integrated switch capability reduces external component count. Verify that the 60mA output current aligns with the target LED string requirements.
Part Context
Fremont Micro Devices specializes in power management and non-volatile memory solutions. This part belongs to their offline switcher portfolio, targeting efficient LED illumination designs without requiring secondary side feedback components.
Replacement Considerations
Consult official substitution lists from Fremont Micro Devices for verified equivalents. Generic replacements may not match the integrated switch or topology flexibility.
