DC DC Switching Controllers datasheet and documents for LTC3834EUFD#TRPBF

LTC3834EUFD#TRPBF

DC DC Switching Controllers Overview

The LTC3834EUFD#TRPBF is a synchronous step-down controller from Analog Devices, designed for high-efficiency power conversion. It operates with an input voltage range of 4 V to 36 V and supports output voltages from 800 mV to 10 V. The device delivers up to 25 A of output current through its single output channel. Key electrical specifications include a quiescent current of 4 uA and a typical operating supply current of 30 uA. The switching frequency is fixed at 400 kHz, ensuring stable regulation with a load adjustment of 0.1%. The component functions within a temperature range of -40°C to +85°C and utilizes a QFN-28 package.

DC DC Switching Controllers Feature Summary

Synchronous buck topology for enhanced efficiency
Low quiescent current operation for standby applications
Integrated shutdown control capability

DC DC Switching Controllers Applications

Industrial point-of-load regulation
Distributed power systems
Telecommunications infrastructure

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the QFN-28 package variant matches your PCB footprint requirements. Ensure the supplier provides official datasheets to validate the 400 kHz switching frequency and 25 A current rating. Cross-reference the manufacturer part number to avoid confusion with tube-packaged equivalents like the #PBF variants.

DC DC Switching Controllers Selection Notes

Select this controller when a fixed 400 kHz frequency is required for EMI management. The 4 V minimum input voltage suits systems powered by standard bus rails. Consider the 25 A output capability against your thermal design constraints. The low 4 uA IQ makes it suitable for applications requiring efficient power management during idle states.

DC DC Switching Controllers Part Context

This component belongs to the LTC3834 family of synchronous step-down controllers. It shares functional similarities with other parts in the series but differs in package type and packaging format. The EUFD suffix denotes the specific QFN-28 package configuration, distinguishing it from TSSOP or SSOP variants found in the same product line.
