LTC3860EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3860EUH#TRPBF is a dual PolyPhase synchronous step-down switching regulator controller designed for high-current distributed power systems. It operates with an input voltage range of 4V to 60V and supports output currents up to 15A per phase. The device features a constant frequency current mode architecture with a switchable frequency between 250kHz and 835kHz. It utilizes a QFN-32 package and includes independent TRACK/SS pins for synchronized startup sequencing.

DC DC Switching Controllers Feature Summary

• Dual-channel PolyPhase operation minimizes input capacitor ripple current and noise by operating output stages out-of-phase.
• OPTI-LOOP compensation optimizes transient response across a wide range of output capacitance and ESR values.
• Independent ramp control allows precise synchronization of multiple output voltages during startup sequences.

DC DC Switching Controllers Applications

• Automotive always-on systems requiring high efficiency and low quiescent current
• Battery-operated digital devices needing extended operational run time
• Distributed DC power systems in industrial or telecommunications infrastructure

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the EUH designation corresponds to the QFN-32 package variant. Ensure compatibility with external MOSFETs selected for the target current and voltage ratings. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring dual isolated outputs from a single controller with tight tracking requirements. Consider the 4V to 60V input range suitability for automotive or industrial bus architectures. Evaluate thermal performance based on the QFN-32 package capabilities and expected load conditions. Verify that the required switching frequency falls within the adjustable 250kHz to 835kHz range.

DC DC Switching Controllers Part Context

This part belongs to the LTC3860 family of dual synchronous buck controllers. It shares architectural similarities with other PolyPhase controllers but is distinct in its specific input voltage window and package configuration. The EUH suffix differentiates it from tube-packaged variants like the #PBF versions, indicating surface-mount reel packaging for automated assembly.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements require matching dual-channel PolyPhase architecture, similar input voltage ranges, and compatible pinouts.
