DC DC Switching Controllers datasheet and documents for LTC3868IUH#TRPBF

LTC3868IUH#TRPBF

DC DC Switching Controllers Overview

The LTC3868IUH#TRPBF is a dual synchronous step-down switching regulator controller from Analog Devices. It drives all N-channel power MOSFET stages in a buck topology. The device supports an input voltage range of 4V to 24V and delivers up to 25A output current across two independent channels. Operating frequencies are adjustable between 75kHz and 850kHz. It features a low quiescent current of 170µA, load regulation of 0.01%, and operates within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Dual channel architecture with independent control for each phase
Synchronous rectification capability for high efficiency
Integrated soft-start functionality to limit inrush current
Precision current mode control with cycle-by-cycle current limiting

DC DC Switching Controllers Applications

Distributed DC power systems
Battery operated digital devices
Automotive always-on systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation matches the required operating temperature range of -40°C to +85°C. Ensure the QFN-32 package footprint aligns with the PCB layout specifications. Cross-reference the manufacturer datasheet for any recent product change notices regarding pinout or electrical characteristics.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring dual-phase synchronization to reduce input ripple. Consider the 4V to 24V input range compatibility with system rails. Evaluate the 75kHz to 850kHz frequency range against EMI requirements and passive component size constraints. Verify that the 25A total output capability meets the peak load demands of the target design.

DC DC Switching Controllers Part Context

This part belongs to the LTC3868 family of PolyPhase controllers. It is functionally related to variants such as the LTC3868EGN-1 and LTC3868EUH#TRPBF, differing primarily in package type and temperature grade. The series is designed for high-performance synchronous buck converter implementations.
