DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IUF designation corresponds to the industrial temperature grade (-40°C to +125°C). Ensure compatibility with the required QFN-24 package footprint during procurement planning. Cross-reference the manufacturer's latest datasheet for any recent product change notifications or pinout updates before finalizing orders.

DC DC Switching Controllers Selection Notes

Select this component when a single-output buck topology is required with wide input voltage flexibility up to 38V. The differential remote sensing feature makes it suitable for applications where long PCB traces cause significant voltage drop. Consider the 200kHz to 1.2MHz frequency range to balance magnetic component size against switching losses. Verify that the 25A current capability aligns with the peak load requirements of the target system design.

DC DC Switching Controllers Part Context

This part belongs to the LTC3867 family of synchronous buck controllers manufactured by Analog Devices. It is specifically the industrial temperature grade variant housed in a QFN-24 package. The #TRPBF suffix denotes the tape-and-reel packaging format intended for automated surface-mount assembly processes. It serves as a core power management IC for converting higher bus voltages to lower processor or logic supply rails.

DC DC Switching Controllers Replacement Considerations

LTC3867IUF#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Both parts share the same functional capabilities and thermal performance characteristics. Designers must verify that their assembly equipment supports the specific packaging format selected. No functional changes are implied by the packaging difference.
