LT8614MPUDC#PBF

Overview

The LT8614MPUDC#PBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It features an integrated 42V, 4A silent switcher with a fixed 2.5MHz switching frequency. The device operates within an input voltage range of 3.8V to 42V and supports output voltages from 0.6V to 36V. It utilizes a 16-lead (4x4) DFN package rated for junction temperatures up to 150°C.

Feature Summary

Integrates a 42V, 4A synchronous buck switch with low EMI silent switcher technology
Supports wide input voltage range from 3.8V to 42V
Includes programmable soft-start and adjustable switching frequency
Features comprehensive protection mechanisms including overvoltage, undervoltage, and thermal shutdown

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures
Telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'MP' against official Analog Devices documentation to confirm military-grade qualification status. Ensure the order includes the '#PBF' designation for lead-free compliance. Cross-reference the datasheet revision date to validate current technical specifications before procurement.

Selection Notes

Select this component when designing high-voltage synchronous buck converters requiring low electromagnetic interference. The fixed 2.5MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the required output current does not exceed the 4A continuous limit under maximum operating temperature conditions.

Part Context

This part belongs to the LT8614 family of silent switcher regulators designed for applications sensitive to conducted and radiated noise. The MP suffix typically denotes enhanced reliability or environmental testing standards compared to commercial variants. It serves as a direct replacement for standard LT8614 parts where higher qualification levels are mandated.
