Procurement Notes
Verify the product status, which is listed as obsolete, before procurement planning. Confirm the manufacturer origin, noting references to both Cypress Semiconductor Corp and Infineon Technologies due to corporate acquisition history. Ensure the specific package type matches the design requirements, as sources indicate variations such as LQFP or QFN. Validate the part number against official datasheets to confirm compatibility with existing system designs.
Selection Notes
Select this component for applications requiring a multi-channel buck converter for LED control. Consider the absence of internal switches when designing external power stages. Evaluate the thermal performance within the specified -40°C to 85°C ambient temperature range. Verify that the 22V to 26V input supply aligns with the system's power architecture. Note the obsolete status may impact long-term availability.
Part Context
This component belongs to the PMIC category, specifically under LED Drivers. It is part of the S6AL211 series from Cypress Semiconductor, which focuses on intelligent lighting solutions. The manufacturer has undergone acquisition by Infineon Technologies, affecting current branding and documentation sources. The device serves as a dedicated controller for managing multiple LED channels efficiently.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, alternative sourcing should be verified through official Infineon or authorized distributor channels for compatible legacy replacements.
