Procurement Notes
Verify the obsolete status before procurement planning. Confirm availability through secondary market distributors or existing stock holders. Ensure design-in compatibility with legacy systems requiring this specific pinout and electrical profile. No new production units are available from the manufacturer.
Selection Notes
Select this component only for designs already utilizing the AS3696 architecture. Evaluate alternative drivers if new product development is required due to end-of-life status. Verify that the 4V-5.5V supply range matches the system power budget. Check thermal management requirements for the SMD package within the specified operating temperature limits.
Part Context
This part belongs to the ams OSRAM portfolio of digital photonics and power management solutions. It serves as a specialized interface for controlling LED arrays in consumer and industrial electronics. The manufacturer focuses on integrated circuits for lighting and sensing applications across mobile and computing sectors.
Replacement Considerations
No direct public substitute part numbers are confirmed for this obsolete component. Designers must evaluate functional equivalents from other manufacturers or redesign using current ams OSRAM LED driver families. Cross-reference pinouts and electrical specifications carefully when selecting alternatives.
