LTC3879EMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3879EMSE#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7V to 60V and supports output voltages from 0.6V to 60V. The device integrates high-side and low-side drivers capable of delivering up to 15A of continuous current. It utilizes a proprietary constant frequency, peak current mode architecture with no external sense resistor requirement. The controller features adjustable switching frequencies from 100kHz to 500kHz and includes comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown.
