Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct output voltage and package specifications. Confirm RoHS compliance status through authorized distributors. Cross-reference datasheet revisions to validate pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a fixed 4.8 V output is required from a variable input source up to 10 V. The synchronous design offers superior efficiency compared to asynchronous alternatives. Ensure the application demands a 300 kHz switching frequency and fits within the thermal constraints of the SOT-23-5 package for optimal performance.

Part Context

This component belongs to the S-8357 series of synchronous boost regulators from ABLIC. The series is characterized by high efficiency and low quiescent current consumption. The specific model integrates internal power switches to minimize external component count while maintaining robust performance in compact form factors.

Replacement Considerations

Direct substitutes include other models from the S-8357 series with identical pinouts but different fixed output voltages, such as S-8357F36MC-MGVT2G or S-8357G32MC-MIRT2U. Verify that alternative parts match the required output voltage and current capabilities.
