LTC3882EUJ-1#TRPBF

DC DC Switching Controllers Overview

The LTC3882EUJ-1#TRPBF is a dual-channel PolyPhase DC/DC synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed 500kHz switching frequency and accepts an input voltage range of 7V to 14V. The device provides two independent outputs, supporting configurations such as 1V at 40A or 1.8V at 30A when paired with DrMOS power stages. It utilizes a constant frequency, leading-edge modulation voltage mode architecture for precise output regulation. The component features a PMBus compliant serial interface and is housed in a 40-WFQFN package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration during procurement. Confirm that external DrMOS power stages are selected separately as this component functions strictly as a controller. Ensure design compatibility with the required 7V to 14V input supply rails. Validate thermal management requirements for the 40-QFN package under maximum load conditions.

DC DC Switching Controllers Selection Notes

Select this controller when dual independent low-voltage high-current outputs are required from a single IC. It is suitable for designs needing digital monitoring via PMBus rather than analog-only control. Consider the fixed 500kHz frequency against application size constraints. Verify that the external power stage selection matches the internal driver capabilities and thermal limits.
