Procurement Notes

Verify the complete part number including suffixes such as 'G' or 'U' which may indicate specific packaging or environmental compliance variations. Confirm RoHS status and REACH compliance requirements against your project specifications. Ensure the ordering quantity aligns with manufacturer standard packaging multiples. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Selection Notes

Select this component when a fixed 6.5V output is required from a variable input source between 0.9V and 10V. The 345kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the SOT-23-5 footprint constraints during PCB layout. Verify that the load current requirements do not exceed the internal switch capabilities defined in the electrical characteristics table.

Part Context

This device belongs to the S-8355 series of boost switching controllers from ABLIC Inc. The series utilizes CMOS technology to achieve high efficiency and low power consumption. Similar models in the family offer different fixed output voltages, such as 3.3V or 5.0V, while maintaining the same pinout and control interface for design flexibility.

Replacement Considerations

Direct substitutes include other S-8355 variants with different output voltages if the system allows for adjustment, such as S-8355M33MC-MDYT2G for 3.3V output. Ensure any replacement maintains the SOT-23-5 package and compatible operating voltage ranges. Verify thermal performance and switching frequency similarities to avoid redesigning passive components.
