Procurement Notes

Verify the specific suffix NCAT2G against official ABLIC documentation to confirm pinout, tolerance, and packaging details. Ensure compatibility with the target PCB footprint for the SOT-753 package. Cross-reference the datasheet revision date to validate current specifications before finalizing procurement plans.

Selection Notes

Select this component when a fixed 15 V output is required from a low-voltage source within the 0.9 V to 10 V range. The 600 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the SOT-753 package size constraints and the operating temperature range requirements of the end application.

Part Context

This part belongs to the S-8355 series of step-up switching regulator controllers. The series is characterized by its small form factor and integrated control logic designed for portable applications. It represents ABLIC's focus on high-efficiency power management solutions using advanced CMOS processes.

Replacement Considerations

Check the S-8355/56/57/58 family datasheet for potential substitutes with different output voltages or control modes. Verify pin-to-pin compatibility if replacing with other SOT-23-5 or SOT-753 packaged controllers from ABLIC or other manufacturers.
