IR2520DPBF

Lighting, Ballast Controllers Overview

The IR2520DPBF is a ballast controller IC designed for fluorescent lamp applications, manufactured by Infineon Technologies. It operates within a frequency range of 34 kHz to 86 kHz and supports a supply voltage range of 11.4 V to 15.4 V. The device draws a supply current of 10 mA and functions reliably across an operating temperature range of -25°C to +125°C. Housed in an 8-PDIP package with through-hole mounting, this component integrates control logic for managing lamp ignition and operation without external dimming capabilities.

Lighting, Ballast Controllers Feature Summary

• Integrated ballast controller optimized for standard fluorescent lamp circuits
• Operates at frequencies between 34 kHz and 86 kHz for efficient lamp driving
• Robust thermal performance suitable for high-temperature environments up to 125°C

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast systems
• Lighting control circuitry
• Commercial lighting fixtures

Lighting, Ballast Controllers Procurement Notes

Verify the obsolete status before procurement as the manufacturer has discontinued this part. Confirm that the 8-PDIP through-hole package aligns with existing PCB footprints. Ensure design-in timelines account for potential lead times associated with end-of-life components or alternative sourcing strategies.

Lighting, Ballast Controllers Selection Notes

Select this component for designs requiring a dedicated ballast controller with fixed frequency operation. It is suitable for applications where through-hole mounting is preferred over surface mount technology. Consider the absence of dimming features when evaluating compatibility with system requirements.

Lighting, Ballast Controllers Part Context

This part belongs to the IR2520 family of ballast controllers. It serves as a specialized integrated circuit for managing the electrical characteristics of fluorescent lamps. The DIP packaging distinguishes it from surface-mount variants like the IR2520DSTRPBF, offering different assembly options for legacy or specific industrial designs.

Lighting, Ballast Controllers Replacement Considerations

The IR2520DSTRPBF is a surface-mount equivalent within the same product family. Verify pinout compatibility and package differences if substituting. No other direct public substitutes are confirmed.
