Overview
The IS31LT3117-ZLS4 is a four-channel linear LED driver IC from Lumissil Microsystems, designed for constant current regulation. It operates within a supply voltage range of 6V to 53V and delivers up to 350mA per channel. The device features an internal switching mechanism and supports PWM dimming. It is housed in an eTSSOP-16 package measuring 5.0mm x 6.4mm. The component functions across a temperature range of -40°C to 125°C (TA) and includes over-temperature protection.
Feature Summary
- Four independent output channels for simultaneous LED control
- Integrated linear topology with internal switching capability
- Supports pulse-width modulation (PWM) dimming signals
- Includes over-temperature protection for thermal safety
Applications
- General LED lighting systems
- Automotive exterior lighting applications
- Industrial illumination fixtures
Procurement Notes
Verify the specific ordering suffix ZLS4 against the manufacturer's latest datasheet to confirm pinout and packaging dimensions. Confirm RoHS3 compliance status directly with the supplier. Ensure the procurement source provides valid traceability documentation. Check for any recent product change notices that may affect mechanical or electrical specifications before finalizing orders.
Selection Notes
Select this component when designing circuits requiring four isolated constant current outputs from a single integrated circuit. It is suitable for applications where a wide input voltage range up to 53V is necessary. Consider the eTSSOP-16 package constraints for PCB layout. Verify that the required channel current does not exceed 350mA per output leg.
Part Context
This part belongs to the IS31LT3117 series of LED drivers from Lumissil Microsystems. The series is characterized by high-voltage operation and multi-channel integration. Evaluation boards such as the IS31LT3117-ZLS4-EB are available for design verification. The family targets efficient power management in compact lighting designs.
