LTC3851AIGN#TRPBF

DC DC Switching Controllers Overview

The LTC3851AIGN#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 with a constant frequency current mode architecture. The device supports a phase-lockable switching frequency ranging from 250 kHz to 750 kHz. It operates with an input voltage range of 4 V to 38 V and can deliver up to 25 A output current. The output voltage is programmable from 800 mV to 5.5 V. It features load regulation of 0.01% and operates within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the A-grade designation meets the extended temperature requirements of -40°C to +125°C for your application environment. Ensure the SSOP-16 package dimensions align with your PCB footprint design constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when driving high-current loads using external N-channel MOSFETs is required. The adjustable frequency range allows optimization for size versus efficiency trade-offs. Consider the 4 V to 38 V input range compatibility with your system bus voltages. The integrated tracking feature supports multi-rail sequencing requirements common in complex digital systems.

DC DC Switching Controllers Part Context

This part belongs to the LTC3851 family of synchronous buck controllers. It shares architectural similarities with the LTC3850 but offers single-output configuration. The device is designed for applications demanding high efficiency and fast transient response. It complements other Analog Devices PMIC solutions by providing flexible external power stage control.
