• General purpose DC-DC conversion systems

Procurement Notes

Verify the complete part number including suffixes such as O2ST2G against official ABLIC documentation to ensure correct package and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets or environmental reports before finalizing procurement orders.

Selection Notes

Select this component when a compact, single-output boost controller is required. Ensure the external inductor and capacitor values match the internal switching frequency requirements. Verify that the input voltage range supports the specific application's source conditions.

Part Context

This component is part of the S-8357 series from ABLIC Inc., which focuses on efficient power management solutions. The series targets applications needing reliable voltage stepping in small form factors. It complements other PMIC offerings like the S-8354 and S-8358 families.

Replacement Considerations

Check for direct pin-compatible substitutes within the S-8357 family with different output voltages. Cross-reference electrical parameters such as switching frequency and operating temperature range with alternative boost controllers from other manufacturers if availability is constrained.
