Overview
The IRS2983STRPBF is an AC-DC LED driver controller manufactured by Infineon Technologies, housed in a SOIC-8 package. It operates within a supply voltage range of 10 V to 18 V and supports a switching frequency of 320 kHz. The device features a maximum output current capability of 600 mA and maintains a typical operating supply current of 10 mA. It is designed for flyback or buck-boost topologies and functions reliably across an extended temperature range from -25 °C to +125 °C.
Feature Summary
- Integrated SMPS control IC designed for driving switching ICLs in LED lighting applications
- Supports versatile flyback and buck-boost converter topologies for efficient power conversion
- Provides high efficiency with stable reactions to dynamic load changes
Applications
- AC-DC LED lighting systems requiring high power quality
- Flyback converter designs for general illumination
- Buck-boost topology implementations for constant current LED drivers
Procurement Notes
Verify the specific suffix STRPBF against official Infineon documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with required thermal management solutions given the SOIC-8 form factor and specified power dissipation limits under operational loads.
Selection Notes
Select this component for applications demanding integrated control of flyback or buck-boost converters in LED drivers. Consider the 320 kHz operating frequency and 600 mA output drive capability when sizing external magnetic components and switches. Validate that the system input voltage aligns with the specified 10 V to 18 V operating range.
Part Context
This part belongs to Infineon's portfolio of AC-DC LED driver controllers, which aim to deliver excellent power quality and high efficiency. These controllers support dimming levels down to 0.1% and minimize external component counts to reduce overall system cost while maintaining robust performance in dynamic load conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Infineon cross-reference guides for verified alternatives.
