LTC3851IMSE-1#PBF

DC DC Switching Controllers Overview

The LTC3851IMSE-1#PBF is a high-performance synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It features a constant frequency current mode architecture with a phase-lockable switching frequency up to 750kHz. The device drives an all N-channel synchronous power MOSFET stage and supports input voltages from 4.5V to 32V. It provides a single positive output configured for DC-to-DC conversion, operating within a junction temperature range of -40°C to 125°C. The component is housed in a 16-pin MSOP EP package.

DC DC Switching Controllers Feature Summary

Drives all N-channel synchronous power MOSFETs for high efficiency
Constant frequency current mode architecture with phase-lock capability
Integrated soft-start, tracking, and enable functions

DC DC Switching Controllers Applications

High efficiency 3.3V/15A step-down converters
Industrial distributed power systems
General-purpose DC-to-DC regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the MSOP EP package variant matches the design footprint requirements. Ensure the input voltage range aligns with the system supply constraints before integration.

DC DC Switching Controllers Selection Notes

Select this controller when driving all N-channel MOSFETs is required for optimal efficiency. The phase-lockable frequency allows synchronization with other system clocks. Verify that the thermal performance of the MSOP EP package meets the application's heat dissipation needs.

DC DC Switching Controllers Part Context

This component belongs to the LTC3851 family of wide input voltage range synchronous step-down DC/DC controllers. It serves as a control IC rather than an integrated power converter, requiring external power stages. The IMSE-1 designation specifies the industrial temperature grade and MSOP package configuration.
