Overview
The NJW4617DL3-TE1 is a linear constant current LED driver IC from Nisshinbo Micro Devices, designed for single-channel applications. It supports an output current of 500 mA and operates within a supply voltage range of 2.5 V to 40 V. The device features PWM brightness control and is housed in a TO-252-5 package. It functions effectively across a wide temperature range from -40°C to +125°C with a maximum power dissipation of 3.125 W.
Feature Summary
- Linear type constant current regulation for stable LED driving
- Supports PWM dimming control for brightness adjustment
- Wide operating voltage range suitable for various DC sources
Applications
- LED lighting for facilities directly powered by DC voltage
- Stage lighting or amusement lighting systems requiring large current
- Image recognition lighting for factory automation equipment
Procurement Notes
Verify the specific suffix TE1 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation before integration. Ensure the TO-252-5 footprint matches the target PCB design. Check for any updated datasheet revisions that may affect thermal performance parameters.
Selection Notes
Select this component for high-current single-channel LED applications requiring linear regulation. Compare against the NJW4616 if lower current (300 mA) suffices. Consider the NJW4615A for lower voltage requirements. Verify thermal management capabilities given the 3.125 W dissipation limit in the chosen enclosure.
Part Context
This part belongs to the NJW4617 series of linear LED drivers. It complements the NJW4615 and NJW4616 models, offering higher current capacity. The series targets industrial and commercial lighting solutions where flicker-free operation and wide dimming ranges are critical for image recognition and display applications.
Replacement Considerations
Direct substitutes include other parts within the NJW4617 family with compatible pinouts. Cross-reference with NJW4616 for lower current needs. Verify pin compatibility and thermal characteristics before substituting with generic equivalents.
