Procurement Notes
Verify component status carefully as the SC2608BSTRT is listed as obsolete and no longer manufactured by Semtech. Confirm availability through authorized distributors or secondary markets. Ensure that any substitute components meet the original electrical specifications and pinout requirements for seamless integration into existing designs.
Selection Notes
Select this component only if legacy compatibility is required for existing SC2608-based designs. Evaluate alternative active parts from the same family if new production is planned. Consider thermal performance within the specified operating temperature range and ensure the 8-SOIC package fits the target PCB layout constraints.
Part Context
This part belongs to the SC2608 series of simple synchronous voltage mode PWM controllers. It is designed for efficient step-down conversion. The specific suffix indicates the tape and reel packaging format. Other variants in the series include SC2608A and SC2608B, which share similar functional descriptions but may differ in specific electrical parameters or documentation versions.
Replacement Considerations
Public confirmed substitutes are not explicitly listed in the provided source data. The component is marked as obsolete. Designers should consult Semtech's official documentation for recommended replacement strategies or equivalent active parts within the SC26xx family.
