UC2872DWTR

Overview

The UC2872DWTR is a high-performance ballast controller IC manufactured by Texas Instruments, designed for electronic lighting applications. It operates within a frequency range of 57kHz to 78kHz and supports a supply voltage of 4.5V to 24V. The device draws a typical supply current of 6 mA and functions reliably across an operating temperature range of 0°C to 70°C. Packaged in a 16-SOIC surface-mount housing with a width of 7.50mm, it integrates control circuitry for efficient lamp management without requiring external dimming components.

Feature Summary

• Integrated ballast control functionality for electronic lighting systems
• Fixed frequency operation within the 57kHz to 78kHz range
• Surface-mount 16-SOIC package design for compact integration

Applications

• Electronic ballast controllers for fluorescent lamps
• High-frequency AC lighting power supplies
• Commercial and industrial fixed-frequency illumination systems

Procurement Notes

Verify that the ordering suffix 'TR' confirms tape-and-reel packaging rather than tube delivery. Confirm the base part number UC2872 matches the required specifications. Ensure the manufacturer is Texas Instruments and check RoHS3 compliance status. Validate the 16-SOIC package dimensions against PCB footprint requirements before procurement.

Selection Notes

Select this component when a fixed-frequency ballast controller is required for standard fluorescent lighting applications. The UC2872 series provides integrated control without external dimming capabilities. Consider the 16-SOIC package size and 0°C to 70°C operating range for environmental compatibility. Verify supply voltage requirements fall within the 4.5V to 24V range for proper operation.

Part Context

The UC2872 belongs to the UC3872 family of ballast controllers from Texas Instruments. The UC2872 variant typically denotes specific commercial or industrial grade specifications compared to its counterparts. This controller is part of a broader portfolio of power management solutions for lighting applications, offering standardized performance metrics for electronic ballast designs.

Replacement Considerations

Public confirmed substitute part numbers include UC3872DW and UC3872DWG4. These variants share the same SOIC-16 package and core control functionality. Verify pinout compatibility and thermal characteristics when substituting between UC2872 and UC3872 series devices.
