Overview
The IW3605-02C is an LED driver IC manufactured by Renesas Electronics Corporation, designed for AC/DC offline switching applications. It supports Flyback, Buck, and Boost topologies with a single output. The device operates at a frequency of 90kHz and features dimming capabilities. It is housed in an 8-SOIC package (0.154 inch width) with no internal switch. The component has a specified operating temperature range from -40°C to 150°C TJ. It is RoHS compliant and classified as Not Recommended for New Designs.
Feature Summary
- Supports multiple AC/DC offline switching topologies including Flyback, Buck, and Boost configurations.
- Integrated dimming functionality for LED control applications.
- Operates within an extended industrial temperature range up to 150°C junction temperature.
Applications
- LED lighting systems utilizing AC/DC offline power supplies
- Flyback converter based LED drivers
- Buck or Boost topology LED illumination circuits
Procurement Notes
Verify the specific suffix 'C' against official Renesas documentation, as primary sources list 'IW3605-02'. Confirm current status as Not Recommended for New Design due to potential minimum order quantity restrictions. Ensure compatibility with existing designs rather than new development. Check for any Product Change Notices regarding packaging or labeling updates before procurement.
Selection Notes
Select this component for legacy AC/DC offline LED driver designs requiring Flyback, Buck, or Boost topologies. Verify that the 8-SOIC package fits the PCB layout constraints. Consider the 90kHz switching frequency for EMI management. Evaluate the absence of an internal switch against system requirements. Confirm suitability for the required thermal environment given the 150°C TJ limit.
Part Context
The IW3605 belongs to Renesas' portfolio of LED driver integrated circuits. It is part of the broader IW series focused on power management for lighting applications. The device is categorized under PMIC LED drivers. It is distinct from Renesas microcontrollers like the RX or RA series. The product line targets general-purpose LED driving needs in offline power conversion scenarios.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for cross-reference information. Verify pinout and electrical parameter compatibility if considering alternative components from other manufacturers.
