LTC3865IUH-1#TRPBF

DC DC Switching Controllers Overview

The LTC3865IUH-1#TRPBF is a dual-phase synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 38 V and supports output voltages from 600 mV to 5 V. The device delivers up to 25 A of output current with a switching frequency of 770 kHz. It features a QFN-32 package, operates between -40°C and +125°C, and includes pin-selectable outputs.

DC DC Switching Controllers Feature Summary

• Dual-phase synchronous buck control architecture
• Pin-selectable output configuration options
• Integrated soft-start and power good monitoring

DC DC Switching Controllers Applications

• Industrial distributed power systems
• Telecommunications infrastructure
• Point-of-load regulation for high-current loads

DC DC Switching Controllers Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging versus #PBF tube packaging when sourcing. Confirm regional availability as distribution channels may restrict supply. Ensure the specific variant matches design requirements for input voltage and thermal performance before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring dual independent outputs from a single controller. Consider the 38 V maximum input limit and 25 A current capability against load demands. Evaluate the QFN-32 thermal dissipation characteristics for the intended enclosure environment.

DC DC Switching Controllers Part Context

This part belongs to the LTC3865 series of dual-phase synchronous step-down controllers. It shares architectural similarities with other devices in the family but differs in specific pin configurations and output selection methods defined by the suffix.
