Procurement Notes
Verify the specific suffix 'RTER' against the manufacturer's official documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure that the ordering information matches the exact part number variant required for your design, as suffixes may indicate differences in packaging or environmental certifications rather than functional changes.
Selection Notes
Select this component when designing circuits requiring multiple regulated LED channels from a low-voltage source. The integrated charge pump eliminates the need for external inductors, simplifying layout. Consider the thermal performance within the WQFN package and ensure the application environment stays within the specified operating temperature limits for optimal longevity.
Part Context
This part belongs to the TPS60255 series of LED lighting drivers. It is specifically engineered for applications demanding high efficiency and compact form factors. The device integrates necessary power stages and control logic into a small footprint, reducing the bill of materials compared to discrete solutions.
Replacement Considerations
The TPS60255RTERG4 is a verified equivalent part number representing the same device with lead-free plating and RoHS compliance. Verify pinout compatibility and electrical specifications before substitution.
