UC2871QTR

Overview

The UC2871QTR is a resonant fluorescent lamp driver manufactured by Unitrode. It operates within a frequency range of 57kHz to 78kHz and supports a supply voltage of 4.5V to 20V. The device delivers an output current of 0.1A and utilizes a 20-PLCC (J-Lead) package with dimensions of 9x9mm. It functions as a bipolar controller designed for lighting applications.

Feature Summary

Integrated cycle-by-cycle current limiting for enhanced protection
Designed specifically for resonant fluorescent lamp driving
Operates as a dedicated ballast controller

Applications

Resonant fluorescent lamp drivers
LCD supply modulation
Ballast control systems

Procurement Notes

Verify the manufacturer origin, as Unitrode assets are now managed by Texas Instruments. Confirm the specific suffix QTR indicates tape-and-reel packaging versus other variants. Ensure the component matches the 20-PLCC physical footprint and electrical specifications required for the target circuit design before procurement.

Selection Notes

Select this component for applications requiring a dedicated resonant fluorescent lamp driver. Ensure the operating frequency range of 57kHz to 78kHz aligns with the transformer design. Verify that the 4.5V to 20V supply voltage range is compatible with the system power rails and that the 0.1A output current meets the load requirements.

Part Context

The UC2871 belongs to the UC1871/UC2871/UC3871 family of resonant fluorescent lamp drivers. These components are widely used in lighting applications requiring efficient ballast control. The UC2871 variant specifically addresses commercial and industrial lighting needs with integrated protection features.

Replacement Considerations

The UC1871 and UC3871 are part numbers within the same functional family. Verify pin compatibility and temperature ranges when substituting between these variants.
