Procurement Notes

Verify the specific suffix K3NT2G against official datasheets to confirm pinout and marking codes. Confirm RoHS compliance status through manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 5.4 V output is required from a single-cell lithium-ion source. Ensure the external inductor selection aligns with the 100 kHz switching frequency and desired load current requirements.

Part Context

This part belongs to the S-8352 series, which focuses on low-power step-up regulation. It shares architectural similarities with the S-8351 and S-8353 series but offers distinct output voltage options and control characteristics tailored for specific portable applications.

Replacement Considerations

Direct substitutes include other S-8352 variants with different output voltages or the S-8351 series. Verify compatibility regarding package dimensions and electrical parameters before substitution.
