Overview
The IS31FL3265A-ZLS4-TR is a linear LED driver IC featuring 18 high-voltage constant current channels. It supports an input voltage range of 4.75 V to 40 V and delivers 60 mA per channel. The device utilizes an eTSSOP-28 package (9.7mm x 6.4mm) and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides 18 independent constant current output channels for high-voltage LED applications
- Supports wide input voltage range up to 40V for flexible power supply designs
- Integrated linear regulation ensures stable current drive without external inductors
Applications
- LED lighting modules requiring high-voltage constant current drive
- Automotive interior and exterior illumination systems
- Industrial indicator and signaling arrays
Procurement Notes
Verify the specific suffix ZLS4 against the manufacturer's latest datasheet to confirm pinout, thermal pad configuration, and tape-and-reel specifications. Ensure the design accounts for the linear topology's thermal dissipation requirements given the 60mA per channel output capability and operating temperature range.
Selection Notes
Select this component when designing circuits that require multiple high-voltage LED channels with precise current control. The linear architecture simplifies PCB layout by eliminating inductive components. Consider thermal management strategies due to the power dissipation inherent in linear regulation at higher input-to-output voltage differentials.
Part Context
This part belongs to the IS31FL3265A series from Lumissil Microsystems, specialized for LED lighting drivers. The series focuses on providing reliable constant current solutions for applications demanding high voltage tolerance and multiple channel integration within compact surface-mount packages.
Replacement Considerations
Check for direct substitutes within the IS31FL3265A family or other 18-channel linear LED drivers from Lumissil. Verify compatibility regarding package dimensions, pin assignments, and electrical characteristics before substitution.
