LTC3868EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3868EUH#TRPBF is a synchronous step-down DC/DC switching controller manufactured by Analog Devices Inc. It features two independent output channels, each capable of driving up to 25 A. The device operates with an input voltage range of 4 V to 24 V and supports adjustable output voltages from 800 mV to 14 V. The switching frequency is programmable between 75 kHz and 850 kHz. It utilizes a 32-WFQFN package with exposed pad for surface mount installation.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture providing independent control over two separate power rails
• Integrated synchronous rectification drivers for high efficiency operation
• Programmable switching frequency allows optimization for size and performance
• Supports phase-locked loop synchronization for multi-unit expansion

DC DC Switching Controllers Applications

• Point-of-load regulation in telecommunications infrastructure
• Power distribution networks for industrial equipment
• Voltage regulation for embedded computing systems
• High-current bias supplies for FPGA or ASIC cores

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EUH designation corresponds to the 32-QFN package variant. Ensure compatibility with the required thermal dissipation requirements for the selected operating environment. Check current availability status as supply constraints may affect lead times.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated outputs are required from a single controller IC. The wide input voltage range suits applications powered by 12 V or 24 V buses. Consider the thermal performance of the QFN package for high current loads. Verify that the external component selection supports the desired switching frequency range.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of power management integrated circuits. It serves as a controller requiring external MOSFETs and inductors to complete the power stage. The design focuses on high efficiency and compact footprint solutions for dense PCB layouts.

DC DC Switching Controllers Replacement Considerations

LTC3868EUFD-1#TRPBF offers identical electrical specifications but utilizes a QFN-28 package instead of the 32-QFN form factor.
