Overview
The S-8533A15AFT-TB-U is a switching controller manufactured by ABLIC Inc., designed for buck regulator applications. It operates with a maximum switching frequency of 345kHz and delivers an output current capability of 0.1A. The device utilizes CMOS technology and is housed in an 8-pin PDSO package, specifically identified as 8-TSSOP in distributor listings. It supports a minimum operating temperature range starting from unspecified lower limits up to a maximum of +85°C.
Feature Summary
- Functions as a positive output step-down DC-DC controller
- Utilizes CMOS technology for switching control
- Designed for surface mount integration
Applications
- Buck regulator circuit design
- Positive output step-down power conversion
- DC-DC controller implementation
Procurement Notes
Verify the specific manufacturer datasheet for the S-8533A15AFT-TB-U to confirm all electrical parameters and mechanical dimensions. Ensure compatibility with system voltage requirements and thermal management needs. Cross-reference official documentation to validate the 8-TSSOP package type and 345kHz switching frequency specifications before integration into final designs.
Selection Notes
Select this component for applications requiring a dedicated buck regulator controller with CMOS interface characteristics. Consider the 0.1A output current limit and 345kHz switching frequency when designing the external inductor and capacitor network. Verify that the +85°C maximum operating temperature aligns with the environmental conditions of the target application.
Part Context
This part belongs to the broader category of power management ICs, specifically within the DC-DC switch controllers segment. It serves as a control unit for regulating voltage levels in electronic systems, distinct from complete integrated power stages by requiring external power switches and passive components for full operation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official ABLIC documentation or authorized distributors for verified equivalent components.
