IW380-40C

Overview

The IW380-40C is a high-resolution, single-stage non-isolated buck LED driver controller manufactured by Renesas Electronics. Designed for commercial lighting applications, it operates with an optimal input voltage of 78V and supports output power up to 150W. The device features True DC dimming technology, providing flicker-free performance across a dimming range from 0.0625% to 100%. It integrates an internal MOSFET and supports multiple dimming interfaces including PWM, analog, and 0-10V inputs. The component is housed in a compact SOIC-10 package.

Feature Summary

• Integrates True DC dimming technology for ripple-free light output across the entire dimming range
• Supports versatile dimming compatibility via PWM, analog, and 0-10V input signals
• Includes comprehensive protection mechanisms such as input OVP, UVLO, OSP, and OTP

Applications

• Commercial solid-state lighting systems
• Second-stage post-regulation in AC/DC lighting converters
• Stage lighting fixtures requiring high-resolution control

Procurement Notes

Verify the specific suffix 'C' against official Renesas documentation to confirm temperature grade or tape/reel specifications. Confirm current availability status as supply conditions may vary. Ensure the selected variant matches the required operating temperature range and packaging format for the target design.

Selection Notes

Select this component for designs requiring high-efficiency buck conversion with precise current regulation accuracy of ±3%. It is suitable for applications demanding wide input voltage ranges and advanced dimming capabilities without external flicker mitigation components. Consider the SOIC-10 footprint for space-constrained PCB layouts.
