Procurement Notes

This component is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability should focus on third-party surplus distributors or stockholders rather than direct manufacturer allocation. Engineering teams must initiate replacement part selection immediately due to the confirmed end-of-life status.

Selection Notes

Designers should evaluate alternative components from the same product family or newer generations that offer similar channel counts and current capabilities. Compatibility checks regarding package dimensions, pinout configurations, and thermal performance are essential when transitioning to substitute parts to ensure seamless integration into existing hardware layouts.

Part Context

The ISL97636 series belongs to Renesas' portfolio of integrated power management solutions tailored for display technologies. These drivers consolidate boost conversion and current regulation into a single compact package, reducing board space and simplifying design complexity for medium-sized TFT-LCD applications requiring uniform illumination across multiple LED strings.

Replacement Considerations

Public documentation identifies the ISL97678IRZ-T as a similar substitute part number offered by Renesas Electronics Corporation for this discontinued component.
