DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the QFN-28 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet for any recent manufacturing changes or pinout updates.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck outputs are required from a single controller. It is suitable for applications demanding high current density in a compact form factor. Consider the 4V to 24V input range compatibility with your system bus. Evaluate thermal performance based on the 25A per channel capability and ambient conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC3850 family of dual-phase synchronous step-down controllers. It shares architectural similarities with other members like the LTC3850 but offers specific output configurations. The series is designed for high-efficiency power conversion in space-constrained environments.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3850IUF#PBF for similar dual-channel performance. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
