Procurement Notes
Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage and package variant. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference datasheet revisions to validate current specifications and marking changes. Ensure supply chain sources provide authentic components matching the manufacturer's standard packaging requirements.
Selection Notes
Select this component when a fixed 3.0V output is required from an input range starting at 0.9V. The 600kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the application does not require synchronous rectification, as this model uses a non-synchronous topology. Ensure the load current requirements align with the external MOSFET capabilities rather than internal limits.
Part Context
This device belongs to the ABLIC S-8355/56/57/58 series of CMOS step-up switching regulators. The series is characterized by its ability to operate from very low input voltages and its compact footprint. The S-8355 variant specifically denotes the base controller family with fixed output options determined by the alphanumeric suffix codes.
