Overview
The UC2871N is a resonant fluorescent lamp driver integrated circuit manufactured by Texas Instruments. It operates within a switching frequency range of 57 kHz to 78 kHz and is housed in an 18-pin PDIP package with a width of 0.300 inches (7.62 mm). The device functions as a current-mode controller designed specifically for lighting applications.
Feature Summary
- Integrated current-mode control architecture for resonant fluorescent lamp drivers
- Fixed operating frequency range optimized for standard ballast designs
- Through-hole mounting capability via 18-pin DIP package
Applications
- Resonant fluorescent lamp ballasts
- Fluorescent lighting controllers
- Lighting power management systems
Procurement Notes
Verify component status carefully, as the UC2871N is listed as obsolete or no longer manufactured by Texas Instruments. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine and match the specified 18-DIP package and electrical characteristics before integration into design projects.
Selection Notes
Select this component only if designing for legacy resonant fluorescent lamp architectures requiring a dedicated current-mode controller. Consider the obsolete status when planning long-term production cycles. Evaluate alternative modern controllers if new designs require active supply chain support and updated manufacturing timelines.
Part Context
The UC2871 belongs to the Texas Instruments unitrode series of power management ICs. It is categorized under Lighting, Ballast Controllers within the PMIC family. The N suffix denotes the standard plastic DIP package variant suitable for through-hole assembly on printed circuit boards.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation due to the component's obsolete status. Designers should consult Texas Instruments for current equivalent recommendations or evaluate generic resonant lamp controllers with compatible pinouts and frequency ranges.
