LTC3851EMSE-1#TRPBF

DC DC Switching Controllers Overview

The LTC3851EMSE-1#TRPBF is a high-performance synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It drives an all N-channel synchronous power MOSFET stage to deliver regulated DC-to-DC conversion. The device supports an input voltage range of 4.5V to 32V and provides a single positive output configured for up to 15A current capability in typical applications. The switching frequency is adjustable between 250kHz and 750kHz, with a maximum duty cycle of 99%. It operates within a temperature range of -40°C to 85°C and is housed in a 16-lead SSOP package.

DC DC Switching Controllers Feature Summary

Drives an all N-channel synchronous power MOSFET stage for high efficiency
Features a constant frequency current mode architecture
Includes integrated control characteristics such as current limiting, enable, frequency control, soft start, and tracking

DC DC Switching Controllers Applications

High efficiency 3.3V/15A step-down converter designs
1.8V/5A converter applications utilizing pulse skip operation
General purpose synchronous buck regulator implementations

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm that the EMSE variant corresponds to the standard commercial grade specifications rather than the extended A-grade performance. Ensure the 16-SSOP footprint matches the target PCB layout requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous buck controller capable of driving external N-channel MOSFETs is required. It is suitable for designs needing an input voltage up to 32V and adjustable frequencies up to 750kHz. Consider the 16-SSOP package size and the -40°C to 85°C operating range against thermal and spatial constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC3851 family of synchronous step-down switching regulator controllers. The family includes variants like the LTC3851A which offer extended input ranges and higher temperature ratings. The base model provides the core control logic for efficient power management in multi-phase or single-phase DC-DC conversion systems.
