LTC3882EUJ-1#PBF

DC DC Switching Controllers Overview

The LTC3882EUJ-1#PBF is a dual-channel, PolyPhase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It utilizes a constant frequency, leading-edge modulation voltage mode architecture to deliver excellent transient response and output regulation. The device features a PMBus compliant serial interface for digital power system management. Designed for high-density applications, it supports input voltages from 7V to 14V and provides two independent positive outputs. The component is housed in a 40-WFQFN exposed pad package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging compatible with standard SMT assembly processes. Confirm that the EUJ variant corresponds to the specified 40-QFN package dimensions. Ensure compatibility with the intended PMBus implementation requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when dual independent buck outputs are required within a single package footprint. The PolyPhase technology allows for interleaved operation to reduce input and output ripple currents. Consider the 500kHz switching frequency for balancing efficiency and passive component size against transient load requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3882 family of PolyPhase controllers. It serves as a companion to external power stages, such as DrMOS modules or discrete MOSFETs, to create complete DC/DC converter solutions. The -1 suffix typically denotes specific internal configuration options compared to the base model.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the LTC3882EUJ#PBF for functional equivalence if the -1 suffix variations are not critical to the design.
