DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards. Confirm the MPDE package designation matches the required 12-DFN footprint. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability. Check for any recent production change notices affecting electrical characteristics or packaging.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 60V is required alongside extended temperature capabilities down to -55°C. The low quiescent current makes it suitable for energy-efficient designs. Consider the 12-DFN package size for space-constrained applications. Verify that the external component selection supports the desired switching frequency and output current requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3864 family of synchronous buck controllers. It shares core architectural similarities with other devices in the series but is distinguished by its military-grade temperature rating and specific package configuration. The family is designed for versatile DC/DC conversion applications requiring high reliability and efficiency.

DC DC Switching Controllers Replacement Considerations

LTC3864IDE#PBF offers similar electrical performance but with a standard industrial temperature range (-40°C to 125°C). Verify if the extended temperature capability of the MPDE variant is strictly necessary for the application environment before substituting.
