LT8614HUDC#TRPBF

Overview

The LT8614HUDC#TRPBF is a synchronous step-down Silent Switcher regulator from Analog Devices, designed for high-efficiency power conversion. It features an input voltage range of 3.4 V to 42 V and delivers up to 4 A of output current. The device integrates two internal N-channel MOSFETs and supports adjustable switching frequencies between 200 kHz and 3 MHz. It operates with a quiescent current of 1.7 uA and includes programmable soft-start, frequency synchronization, and tracking capabilities. The component is housed in a compact 18-lead QFN package and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

Silent Switcher technology minimizes radiated electromagnetic interference without requiring external ferrite beads or complex layout techniques.
Integrated synchronous rectification provides high efficiency across wide load and line conditions.
Supports phase-shifted multi-phase operation for enhanced current sharing and thermal performance.

Applications

Industrial automation systems requiring isolated or non-isolated DC-DC conversion
Automotive electronics operating within standard voltage architectures
Telecommunications infrastructure power distribution networks

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for quality assurance purposes. Cross-reference the full part number against the latest datasheet revision to confirm pinout and electrical specifications match design requirements exactly.

Selection Notes

Select this component for designs requiring low electromagnetic interference and high efficiency in space-constrained environments. The wide input voltage range accommodates various bus voltages common in industrial and automotive sectors. Consider the thermal performance of the QFN package and ensure adequate PCB copper area for heat dissipation during high-load operations.

Part Context

This part belongs to the LT8614 family of Silent Switcher regulators, which are engineered to reduce radiated emissions significantly compared to traditional buck converters. The family offers flexibility in switching frequency and configuration options, making it suitable for sensitive analog circuits alongside digital power stages.
