LTC3858IGN-1#PBF

DC DC Switching Controllers Overview

The LTC3858IGN-1#PBF is a dual-channel, low quiescent current synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 38V and supports output voltages from 0.8V to 24V. The device features a constant-frequency current mode architecture with a phase-lockable switching frequency between 75kHz and 850kHz. It utilizes out-of-phase operation for two channels to minimize input capacitor ESR losses. Key control features include enable, frequency control, power good indication, and soft start. The component is housed in a 28-lead SSOP package and functions as a DC-to-DC buck converter controller.
