Overview
The IS31LT3135-V1GRLS2-TR is a dual linear programmable current regulator designed for LED lighting applications. It features two independently controlled output channels, supporting main and sub-dual configurations. The device operates within an input voltage range of 1.13V to 1.21V and provides regulated output currents of 300mA and 500mA. Packaged in an 8-SOP (SOIC) format, it integrates advanced control modes including 2-dimensional auto breathing and pattern functionality.
Feature Summary
- Dual independent output channels for flexible LED configuration
- Integrated 2-dimensional auto breathing mode for dynamic lighting effects
- Programmable current regulation with dedicated pattern mode support
Applications
- Main/sub dual-channel LED driver circuits
- Automotive interior lighting systems
- Residential general lighting fixtures
Procurement Notes
Verify the specific suffix V1GRLS2-TR against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure the target application voltage aligns with the specified 1.13V–1.21V operating range. Cross-reference the 8-SOP package dimensions with PCB footprint requirements before finalizing component selection.
Selection Notes
Select this component when a compact dual-channel solution with integrated dimming patterns is required. The linear regulator topology suits low-voltage applications where simplicity and cost-efficiency are prioritized over high-power conversion efficiency. Confirm that the 300mA/500mA current ratings meet the specific LED string requirements without exceeding thermal limits.
Part Context
This part belongs to Lumissil’s H-BLLED driver portfolio, which addresses commercial, residential, and automotive markets. It complements other single-channel or higher-current variants by offering a specialized dual-output capability in a small form factor, suitable for space-constrained lighting designs requiring synchronized channel control.
Replacement Considerations
No officially confirmed substitute part numbers are available in public documentation. Direct replacement requires verifying electrical equivalence and pin compatibility with alternative dual-channel linear drivers from Lumissil or other manufacturers.
