Procurement Notes

Verify the specific suffix 'OWFT2G' against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with automotive qualification standards required for your application. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm lead times and production cycles directly with the manufacturer or certified agents before finalizing procurement plans.

Selection Notes

Select this controller when a fixed 2.0 V boost output is required in space-constrained automotive designs. Consider its low IQ for battery-operated systems where standby power is critical. Verify that the external inductor and capacitor values match the internal oscillator frequency and control loop requirements. Ensure the input voltage range aligns with the system's power source characteristics.

Part Context

This component belongs to the S-8355/56/57/58 series of switching regulators. These devices are designed as standalone controllers requiring external power switches and passive components. The series targets high-efficiency DC-DC conversion in portable and automotive electronics, offering a balance of performance and size reduction through advanced CMOS processes.

Replacement Considerations

Direct substitutes include other S-8355 series variants with different output voltages or packages, such as S-8355QxxMC-OWFT2G. Check pinout compatibility and electrical parameters before substitution. Generic replacements may lack automotive qualification or specific package dimensions.
