LTC7815HUHF#PBF

DC DC Switching Controllers Overview

The LTC7815HUHF#PBF is a non-isolated switching controller from Analog Devices, designed for high-efficiency power conversion. It supports three independent outputs with configurable Buck, Buck-Boost, or Boost topologies. The device operates within an input voltage range of 4.5 V to 38 V and delivers up to 25 A output current. Switching frequencies are adjustable between 320 kHz and 2.25 MHz, allowing optimization for size and efficiency. Output voltages can be regulated from 800 mV to 60 V. The component functions reliably across an extended temperature range of -40°C to +150°C and is housed in a QFN-38 surface-mount package.

DC DC Switching Controllers Feature Summary

• Supports three independent output channels with flexible topology configuration including Buck, Buck-Boost, and Boost modes.
• Enables precise regulation of output voltages ranging from 800 mV to 60 V with high current capability.
• Features adjustable switching frequency from 320 kHz to 2.25 MHz to optimize design trade-offs.
• Operates reliably in harsh environments with an extended industrial temperature range.

DC DC Switching Controllers Applications

• Multi-rail power distribution systems in industrial equipment
• Power management units for telecommunications infrastructure
• Server and data center power supply architectures
• Automotive electronic control unit power stages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates a lead-free, RoHS-compliant tube package variant distinct from the tape-and-reel #TRPBF version. Confirm that the QFN-38 package dimensions match the target PCB footprint requirements. Ensure the supplier provides valid traceability documentation for the Analog Devices manufacturer source. Cross-reference the full part number against official distributor catalogs to confirm availability status and authenticity before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when designing multi-output power stages requiring mixed Buck and Boost configurations on a single IC. Evaluate the required output current against the 25 A limit and ensure thermal management solutions support the QFN-38 package dissipation characteristics. Consider the wide input voltage range suitability for varying bus conditions. Verify that the external component selection aligns with the specified frequency range and output voltage constraints for stable operation.

DC DC Switching Controllers Part Context

This component belongs to the LTC7815 series of low IQ switching controllers from Analog Devices. It is categorized under PMIC - Power Management ICs and specifically classified as a Switching Controller. The device complements other multi-phase controllers by offering independent channel control with diverse topology options, serving as a core power management solution for complex system architectures.

DC DC Switching Controllers Replacement Considerations

The LTC7815HUHF#TRPBF serves as a direct packaging alternative with identical electrical specifications but utilizes tape-and-reel delivery instead of tubes.
