NJW4616U2-TE1

Overview

The NJW4616U2-TE1 is a two-channel constant current LED driver IC from Nisshinbo Micro Devices, utilizing a boost topology. It supports an input voltage range of 2.5 V to 40 V and delivers up to 300 mA output current per channel with a maximum output voltage of 40 V. The device operates at a frequency of 200 Hz and features PWM dimming capabilities. It includes short circuit and thermal protection mechanisms. The operating temperature range spans from -40°C to +125°C, and it is available in surface-mount packages including Reel, Cut Tape, and MouseReel.

Feature Summary

• Dual-channel constant current control for independent LED string management
• Integrated PWM dimming interface for precise brightness adjustment
• Built-in short circuit and thermal protection for enhanced system reliability

Applications

• Facility LED lighting systems requiring DC direct power
• Stage lighting and amusement lighting systems needing wide dimming ranges
• Industrial automation equipment image recognition lighting where flicker removal is essential

Procurement Notes

Verify the specific suffix TE1 against official datasheets to confirm packaging configuration and reel specifications. Ensure compatibility with the required SMD/SMT mounting style and validate that the 2.5 V to 40 V input range aligns with the target power supply design. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when dual-channel boost conversion is required for high-voltage LED arrays. The 300 mA current rating suits medium-power applications, while the wide input voltage range accommodates various battery or DC bus sources. Consider the -40°C to +125°C operating range for industrial environments. Verify that the 200 Hz switching frequency meets EMI constraints and that PWM dimming resolution satisfies visual performance requirements.

Part Context

The NJW4616U2-TE1 belongs to the NJW4616 series of linear type constant current drivers designed by Nisshinbo Micro Devices. This series targets smart society applications, including FA equipment and specialized lighting. The U2 variant specifically denotes the dual-channel configuration, distinguishing it from single-channel models like the NJW4615A or NJW4617 within the same product family.
