Procurement Notes

Verify the complete part number including suffixes to ensure correct output voltage and package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate pinout compatibility and electrical specifications for your specific design requirements.

Selection Notes

Select this controller when a fixed 6.0V output is required from an input range starting at 0.9V. Consider the SOT-23-5 footprint for space-constrained designs. Evaluate the 300kHz switching frequency against EMI constraints and external component size requirements compared to lower-frequency alternatives in the series.

Part Context

This component belongs to the S-8358 series of step-up switching controllers from ABLIC. The series offers various fixed output voltages and low standby currents suitable for battery-operated applications. The S-8358 family shares common interface characteristics but differs in output settings and specific protection thresholds defined by the model suffix.

Replacement Considerations

Direct substitutes include other S-8358 series variants with compatible packages and similar electrical characteristics, such as S-8358E15MC-NSAT2U or S-8358J33MC-NWST2U, provided the output voltage difference is acceptable for the application.
