IR21592STRPBF

Lighting, Ballast Controllers Overview

The IR21592STRPBF is a half-bridge gate driver and dimmable ballast controller manufactured by Infineon Technologies. It operates within a supply voltage range of 12 V to 25 V, with specific operational limits noted between 12 V and 16.5 V in some documentation. The device supports frequencies from 18 kHz to 95 kHz and features a fixed dead time of 1.8 µs. Electrical characteristics include a rise time of 120 ns and a fall time of 65 ns. It draws a typical operating supply current of 25 mA and dissipates up to 1.25 W. The component is housed in a 16-SOIC package and is classified as an end-of-life product.

Lighting, Ballast Controllers Feature Summary

• Integrates half-bridge driver functionality with dedicated dimmable ballast control capabilities.
• Features a fixed internal dead time to prevent shoot-through in high-side and low-side switching applications.
• Supports frequency operation ranges suitable for standard lighting ballast requirements.

Lighting, Ballast Controllers Applications

• Dimmable fluorescent lamp ballast systems
• High-voltage integrated circuit applications requiring half-bridge driving
• Lighting control circuits utilizing photo-flash driver architectures

Lighting, Ballast Controllers Procurement Notes

Verify the discontinuation status before design finalization, as this part is marked as End-of-Life. Confirm availability through secondary market channels or authorized distributors handling excess stock. Ensure that any replacement strategy accounts for the long-term supply risks associated with obsolete components. Validate that the 16-SOIC package dimensions match the existing PCB footprint without modification.

Lighting, Ballast Controllers Selection Notes

Select this component only for legacy designs already utilizing the IR21592 architecture. Consider the fixed 1.8 µs dead time when evaluating switching frequency constraints. Verify that the 12 V to 25 V supply range aligns with the system's power delivery capabilities. Assess the thermal performance given the 1.25 W power dissipation rating in the SOIC-16 package.

Lighting, Ballast Controllers Part Context

This component belongs to Infineon's portfolio of high-voltage integrated circuits designed for power management and lighting applications. It combines gate driving with specific control logic for ballast operations. The STRPBF suffix indicates tape-and-reel packaging for surface-mount assembly. It is distinct from general-purpose drivers like the IR2110 due to its integrated ballast control features.

Lighting, Ballast Controllers Replacement Considerations

The IR21592SPBF is listed as an alternative packaging option for the same functional device. No other direct pin-to-pin substitutes are confirmed in the provided data. Designers should evaluate the IR21592SPBF if reel packaging is unavailable, ensuring identical electrical specifications.
