LTC3839EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3839EUH#TRPBF is a dual-phase synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.75V to 16V and supports output voltages from 0.6V to 5.4V. The device delivers up to 20A of continuous output current per phase, utilizing a constant frequency current mode architecture with switch frequencies adjustable between 100kHz and 1.5MHz. Packaged in a 32-lead QFN (5mm x 5mm) exposed pad for efficient thermal dissipation, it features independent tracking and soft-start capabilities alongside comprehensive protection mechanisms including over-current and thermal shutdown.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'EUH' corresponds to the 32-lead QFN package and '-55C to +125C' temperature grade on the official datasheet. Confirm that '#TRPBF' indicates tape-and-reel packaging with lead-free finish. Cross-reference the manufacturer part number directly with Analog Devices documentation to ensure component authenticity and specification accuracy before integration.

DC DC Switching Controllers Selection Notes

Select this controller when designing high-density power supplies requiring two independent regulated outputs from a single IC footprint. It is suitable for applications needing precise voltage tracking or sequential ramping of multiple rails. Consider the thermal performance of the exposed pad design and the flexibility of the programmable switching frequency range when evaluating system noise and component size constraints.

DC DC Switching Controllers Part Context

This component belongs to the LTC3839 family of PolyPhase controllers designed for high-efficiency power management. It complements other Analog Devices PMIC solutions by providing a compact, dual-output alternative to single-channel controllers. The device integrates advanced features like load line adjustment and low quiescent current operation to support modern low-voltage, high-current digital loads efficiently.

DC DC Switching Controllers Replacement Considerations

LTC3839IUH#TRPBF: Identical electrical specifications but rated for -40C to +125C operating temperature instead of -55C to +125C.
