IRS2980STRPBF

Overview

The IRS2980STRPBF is a DC-DC controller IC from Infineon Technologies, designed for LED lighting applications. It integrates Power Factor Correction (PFC) and ballast control functions in a single chip. The device operates within a supply voltage range of 10 V to 18 V and supports an operating temperature range from -40°C to +125°C. It utilizes an 8-pin SOIC package and features analog and PWM dimming capabilities. The controller is optimized for high efficiency and stable performance in fluorescent lamp systems.

Feature Summary

• Integrates PFC and ballast control functions into a single integrated circuit
• Supports both analog and PWM dimming methods for flexible light control
• Designed for high-efficiency operation in fluorescent lamp applications

Applications

• Fluorescent lamp ballast systems
• Power factor correction circuits for lighting
• LED driver power supplies requiring combined PFC and regulation

Procurement Notes

Verify the specific suffix STRPBF indicates the tape-and-reel packaging format. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the ordering part number matches the exact functional requirements for your design. Check for any updated revision levels that may affect pin compatibility or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a combined PFC and ballast controller is required for fluorescent or compatible LED systems. Consider the 8-pin SOIC package size for PCB layout constraints. Evaluate the need for PWM dimming support versus analog-only solutions. Verify input voltage ranges align with the system's power supply specifications.
