LTC3880EUJ-1#TRPBF

DC DC Switching Controllers Overview

The LTC3880EUJ-1#TRPBF is a dual output PolyPhase synchronous step-down switching regulator controller from Analog Devices. It operates with an input voltage range of 4.5V to 24V and supports output voltages from 500mV to 5.4V. The device features a fixed 1MHz switching frequency and provides up to 30A output current capability per channel. It utilizes a QFN-40 package and functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture supporting independent or parallel operation for high-current applications
• Integrated I2C-based PMBus compatible serial interface for digital power system management
• PolyPhase technology enables automatic phase shedding and load balancing across channels

DC DC Switching Controllers Applications

• High-density server and workstation power distribution
• Telecommunications infrastructure equipment
• Industrial control systems requiring programmable voltage rails

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EUJ designation corresponds to the extended temperature range variant (-40°C to +125°C). Ensure compatibility with required PCB footprint dimensions for the QFN-40 package during procurement planning.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring precise digital monitoring and control via PMBus. The dual-output configuration simplifies board space compared to single-channel solutions. Consider thermal management requirements given the high current capabilities and operating temperature range specified for the EUJ variant.

DC DC Switching Controllers Part Context

This part belongs to the LTC3880 family of PolyPhase controllers designed for demanding power delivery applications. It complements other variants like the standard LTC3880 by offering specific packaging and temperature rating options. The series is widely recognized for its integration of digital management features in compact form factors.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3880EUJ#PBF for tube packaging or the LTC3880IUJ-1#TRPBF for industrial temperature grades. Verify pinout compatibility and software register mapping before swapping between these variants.
