Procurement Notes
Verify the exact suffix against official Infineon documentation to confirm package type and tape/reel specifications. Confirm lifecycle status as components may be marked Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for the 14-pin SSOP variant before procurement.
Selection Notes
Select this controller when a single IC must support various LED power stage topologies. It is suitable for designs requiring PWM dimming and operation across a broad input voltage spectrum. Verify that the 70 mA output current meets the specific drive requirements of the target LED array or configuration.
Part Context
This part belongs to the ILD1151 series of LED lighting driver ICs manufactured by Infineon Technologies. It is specifically engineered as a multitopology high-power LED DC/DC controller. The XUMA1 suffix typically denotes a specific tape and reel packaging format used for automated assembly processes.
Replacement Considerations
Consult official Infineon datasheets for direct pin-to-pin replacements or functional equivalents within the same family. Verify that any substitute component maintains compatibility with the required topology and thermal performance specifications.
