Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct output voltage and package configuration. Confirm that the required external components match the controller's switching frequency and current drive capabilities. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a fixed 3.0V output is required from a variable input source. Ensure the external switch can handle the peak currents generated at the 600kHz operating frequency. Consider thermal dissipation requirements for the PCB layout given the surface-mount packaging constraints.

Part Context

This part belongs to the S-8358 series of switching regulators from ABLIC Inc., which are designed for high-efficiency power management. The series utilizes a combination of PWM and PFM control modes to optimize performance across different load conditions. These controllers are intended for use in space-constrained applications where small footprint and low quiescent current are critical design factors.

Replacement Considerations

Direct substitutes include other variants within the S-8358 family such as S-8358NxxMC-OxPT2U for different voltage outputs. Cross-reference pinouts and electrical characteristics carefully before substitution.
