LTC3807MPFE#TRPBF

DC DC Switching Controllers Overview

The LTC3807MPFE#TRPBF is a military-grade, low quiescent current synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It supports an input voltage range of 4V to 38V and delivers up to 25A of output current with a single output. The device features adjustable switching frequencies from 105kHz to 835kHz and operates within a junction temperature range of -55°C to +150°C. Packaged in a 28-lead TSSOP with exposed pad, it includes integrated soft start, tracking, and cycle-by-cycle current limit protection.

DC DC Switching Controllers Procurement Notes

Verify the MP suffix confirms military grade qualification and traceability requirements. Ensure the TRPBF designation matches reel packaging specifications. Confirm RoHS compliance status and check for any specific lot trace documentation needed for defense procurement standards.

DC DC Switching Controllers Selection Notes

Select this component when high reliability and wide temperature tolerance are critical. Compare against commercial grades if cost is a primary constraint. Verify that the 25A output capability aligns with load requirements and that the 38V input range suits the supply architecture.

DC DC Switching Controllers Part Context

This part belongs to the LTC3807 family of synchronous buck controllers. It shares functional similarities with the LTC3807IFE#PBF but offers enhanced environmental ratings. The series is designed for applications requiring robust performance under extreme conditions while maintaining high efficiency.

DC DC Switching Controllers Replacement Considerations

LTC3807IFE#PBF serves as a commercial alternative. Verify that the lower temperature rating and lack of military certification meet application requirements before substitution.
