LTC7815IUHF#PBF

DC DC Switching Controllers Overview

The LTC7815IUHF#PBF is a non-isolated switching controller from Analog Devices, designed for high-performance power management applications. It integrates three independent output channels capable of operating in buck, boost, or buck-boost topologies. The device supports a wide input voltage range of 4.5V to 38V and delivers up to 25A per channel. It features an adjustable switching frequency between 320kHz and 2.25MHz, allowing optimization for efficiency and component size. The controller operates within a temperature range of -40°C to +150°C and is housed in a compact QFN-38 package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm availability status as supply may be limited. Ensure the QFN-38 package compatibility with your PCB footprint design. Cross-reference the IUHF grade for industrial temperature specifications against your operational requirements.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-rail power architectures needing combined buck and boost functionality. Consider the 38V maximum input voltage limit and 25A current capability for load matching. Evaluate the thermal performance within the QFN-38 package for your enclosure constraints. Compare switching frequency options against electromagnetic interference requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC7815 family of multi-output switching controllers. It shares architectural similarities with other high-channel-count controllers but distinguishes itself through its specific combination of three outputs and wide input voltage range. The series targets complex power management needs in space-constrained environments.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC7815HUHF#TRPBF for tape-and-reel packaging variants. Verify pinout and electrical parameter equivalence before substitution. Consult official documentation for any functional differences between package types.
