Procurement Notes
Verify the specific suffix ZLS4 against the latest datasheet to confirm pinout and thermal pad configuration. Check for Product Change Notifications regarding assembly markings such as TSHT. Confirm availability status as distribution may vary by region. Ensure ESD handling protocols are followed during SMD/SMT installation.
Selection Notes
Select this component when a fixed 60 mA constant current source is required for up to 18 LEDs. The linear topology simplifies design compared to switching regulators but may impact efficiency in high-voltage drop scenarios. Verify that the 28-eTSSOP package fits the PCB layout constraints and thermal requirements of the target application.
Part Context
This part belongs to the IS31FL3265 series of LED drivers from Lumissil Microsystems. The series focuses on providing reliable constant current solutions for various lighting needs. The B variant typically denotes specific electrical characteristics or revisions within the family line, distinguishing it from earlier versions like the A series.
Replacement Considerations
The IS31FL3265A-ZLS4-TR is a related variant within the same product family. Verify if the electrical specifications and pin compatibility allow for direct substitution. Consult official change notifications for any functional differences between the A and B variants before replacing.
