DC DC Switching Controllers Procurement Notes

Verify the exact suffix (e.g., #PBF) as it denotes specific packaging and compliance details. Confirm availability status, as some distributors indicate limited supply or discontinuation. Ensure the selected variant matches the required operating temperature range and pinout configuration for your specific PCB layout requirements.

DC DC Switching Controllers Selection Notes

Select this controller when designing multiphase boost converters requiring precise current sharing and high efficiency. Consider the TSSOP-EP-24 package for thermal performance and board space constraints. Verify that the external MOSFETs and inductors are rated for the specific input and output voltage ranges supported by the 8.5V to 36V input window.

DC DC Switching Controllers Part Context

This component belongs to the LTC3862 series of multiphase controllers. Variants such as the LTC3862EFE-2#PBF offer two outputs, while the -1 suffix typically indicates specific electrical characteristics or package options within the family. These devices are designed for demanding industrial and automotive applications requiring robust power regulation.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the LTC3862 family, such as the LTC3862EFE-2#PBF, if dual-output capabilities are acceptable. Verify pin compatibility and control logic before substituting.
