DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the TSSOP-EP-24 package type matches your PCB footprint requirements. Ensure the 8.5V minimum input voltage aligns with your system's rail specifications before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-phase boost converters requiring precise phase control and synchronization. It is suitable for applications needing wide input voltage ranges up to 36V. Consider the thermal performance of the exposed pad package for high-power density designs.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of multi-phase controllers. The -1 suffix typically denotes specific pinout or functional variations within the series compared to other variants like the -2. It is designed for high-efficiency power conversion in demanding environments.

DC DC Switching Controllers Replacement Considerations

Check for direct substitutes such as LTC3862EFE#PBF or LTC3862IGN#PBF, ensuring pin compatibility and electrical parameter alignment. Verify if alternative packages like QFN-24 are viable for your layout constraints.
