LTC3829EUHF#TRPBF

DC DC Switching Controllers Overview

The LTC3829EUHF#TRPBF is a PolyPhase synchronous buck DC/DC switching controller designed for high-performance multi-phase applications. It supports up to three output phases with a configurable switching frequency ranging from 250 kHz to 770 kHz. The device operates within an input voltage range of 4.5 V to 38 V and delivers a regulated output voltage between 600 mV and 5 V. It features a compact 38-WFQFN (5x7) package with an exposed thermal pad, rated for operation from -40°C to +125°C junction temperature.

DC DC Switching Controllers Feature Summary

• Supports up to three output phases for enhanced current capability and thermal distribution
• Features adjustable switching frequency from 250 kHz to 770 kHz for optimized efficiency and component size
• Includes integrated control characteristics such as current limit, soft start, tracking, and power good indication

DC DC Switching Controllers Applications

• High-density server and workstation power delivery systems
• Industrial equipment requiring robust multi-phase power regulation
• Communication infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when ordering. Confirm the 38-QFN(5x7) package dimensions match the PCB footprint requirements. Ensure the operating temperature range meets the application's thermal constraints. Cross-reference the manufacturer part number directly with Analog Devices documentation to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring up to three parallel buck phases driven by a single IC. It is suitable for applications needing wide input voltage ranges up to 38 V. Consider the thermal performance of the exposed pad design for high-current scenarios. Evaluate the required switching frequency against inductor selection criteria for optimal transient response.

DC DC Switching Controllers Part Context

This component belongs to the PolyPhase series of power management ICs from Analog Devices. It is specifically engineered to drive multiple N-channel MOSFET stages in a synchronous buck configuration. The EUHF suffix denotes the 38-lead QFN package variant, distinguishing it from other package options like the EFE TSSOP version within the same functional family.

DC DC Switching Controllers Replacement Considerations

LTC3829EFE#PBF offers identical electrical functionality but utilizes a TSSOP-38 package instead of the QFN form factor.
