DC DC Switching Controllers datasheet and documents for LTC3834EFE#TRPBF

LTC3834EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3834EFE#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 36 V and supports adjustable output voltages from 800 mV to 10 V. The device delivers up to 25 A of output current with a switching frequency of 400 kHz. Quiescent current is specified at 30 uA during operation and drops to 4 uA in shutdown mode. Load regulation is rated at 0.1%. It functions within a temperature range of -40°C to +85°C and is housed in a 20-lead TSSOP-EP package.

DC DC Switching Controllers Feature Summary

Synchronous buck controller architecture for high-efficiency power conversion
Ultra-low quiescent current capability for optimized standby performance
Integrated shutdown function to minimize power consumption when inactive

DC DC Switching Controllers Applications

Point-of-load regulation in industrial systems
Power management for embedded computing platforms
Telecommunications infrastructure equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration distinct from tube variants like #PBF. Confirm that the IFE designation corresponds to the correct industrial temperature grade (-40°C to +85°C) required for the application environment. Ensure compatibility with the 20-TSSOP-EP footprint and thermal pad requirements during assembly.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring a 4 V to 36 V input range with outputs up to 25 A. The 400 kHz fixed switching frequency allows for balanced passive component sizing. Consider the low 30 uA operating IQ for applications sensitive to standby power draw. Validate that the 20-lead TSSOP-EP package meets thermal dissipation needs for the target current load.

DC DC Switching Controllers Part Context

This part belongs to the LTC3834 family of synchronous step-down controllers. It shares core electrical specifications with other variants such as the LTC3834EGN-1#PBF, differing primarily in package type (TSSOP vs SSOP) and shipping quantity (Reel vs Tube). The device is categorized under PMIC - Power Management ICs within the broader Analog Devices portfolio.
