Procurement Notes
Verify the specific suffix 'G' against official ABLIC documentation to confirm lead-free status and tape-and-reel packaging specifications. Confirm availability as the related S-8533 series models have been subject to discontinuation notifications. Ensure the ordering part number matches the exact electrical parameters required for the target application design.
Selection Notes
Select this component for designs requiring a compact synchronous buck controller with low standby current. The wide input voltage range supports various battery chemistries. Verify thermal requirements for the TSSOP-8 package in high-temperature environments up to 125°C. Ensure compatibility with external MOSFETs and passive components for the intended switching frequency.
Part Context
This model belongs to the S-8533 series of switching controllers from ABLIC. The series provides synchronous rectification capabilities for improved efficiency compared to asynchronous designs. The TSSOP-8 package offers a small footprint suitable for space-constrained portable electronics and industrial applications requiring reliable power regulation.
Replacement Considerations
Related discontinued models include S-8533A14AFT-TB-U and S-8533A30AFT-TB-U. These share similar form factors but may differ in internal reference voltages or timing characteristics. Verify functional equivalence before substitution.
