Procurement Notes
Verify the complete part number including suffixes against official ABLIC documentation to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and packaging type (Reel) prior to ordering. Cross-reference manufacturer datasheets for specific thermal and electrical limits to avoid specification mismatches during integration.
Selection Notes
Select this component when a fixed 5 V output is required from variable or lower input sources. Consider the 100 kHz switching frequency and 25.9 uA quiescent current for efficiency requirements. Ensure the load current does not exceed the specified limits and that the operating temperature range aligns with the application environment.
Part Context
This part belongs to the S-8358 series of switching controllers by ABLIC Inc., which are optimized for step-up topologies. The series offers various output voltage options and packages, catering to diverse power management needs in portable and industrial applications while maintaining high efficiency and compact form factors.
Replacement Considerations
Direct substitutes may include other S-8358 variants with compatible output voltages and packages. Verify pin compatibility and electrical specifications before substitution. Consult ABLIC documentation for approved alternative part numbers within the same family.
