Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact electrical parameters, as variations exist within the series. Confirm RoHS compliance status and packaging details directly with authorized distributors. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference part numbers to avoid confusion with similar models in the S-8358 family.

Selection Notes

Select this component when a fixed 2.6V output is required from a variable or low input source. The 600kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the internal switch limits. Consider thermal performance in the final enclosure design due to the small package footprint.

Part Context

This part belongs to the ABLIC S-8358 series of switching regulators. The series is designed for applications requiring high efficiency and low standby current. These controllers are commonly used in mobile and industrial electronics where space constraints and battery life are critical factors. The S-8358 series offers various fixed output voltages to suit different system requirements.

Replacement Considerations
