Procurement Notes
Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status through manufacturer datasheets or environmental reports before integration into regulated assemblies.
Selection Notes
Select this component when a fixed 3.5V output is required from a single-cell lithium-ion or alkaline battery source. Ensure the external inductor and diode selections support the 300kHz switching frequency and 54.8mA load current while meeting thermal constraints for the SOT-23-5 package.
Part Context
This unit belongs to the S-8357 series of switching controllers, which are designed for compact power management solutions. The series offers various fixed output voltages to accommodate different system requirements while maintaining a small footprint suitable for space-constrained portable electronics.
Replacement Considerations
Cross-reference with other S-8357 variants such as S-8357F50MC-MHJT2U for different voltage outputs. Verify pin compatibility and electrical specifications before substituting with generic boost controllers.
