Procurement Notes
This component is officially discontinued by ABLIC Inc. Public records confirm end-of-life status with notifications dated May and June 2025. Availability is restricted or non-existent through standard distributors like Mouser. Verification of current stock levels or alternative sourcing channels is required before procurement consideration. Legacy support may be limited.
Selection Notes
Designers should note that the S-8533A14AFT-TB-U is no longer in active production. Selection requires careful evaluation of available surplus markets or direct manufacturer legacy inquiries. Due to the discontinued status, long-term supply assurance cannot be guaranteed. Alternative components from the same family or newer generations should be evaluated for new designs to ensure ongoing availability and support.
Part Context
The S-8533A14AFT-TB-U belongs to the S-8533 series of synchronous PWM controllers manufactured by ABLIC Inc. These devices are categorized as PMICs intended for step-down voltage regulation. The '14' suffix typically denotes a specific output voltage setting within the series, while 'TSSOP-8' specifies the package type. The series is designed for applications requiring efficient power management in compact form factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Designers should consult ABLIC's official documentation for recommended replacements or evaluate other synchronous PWM controllers from the S-8533 series that remain in active production.
