LTC3892EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3892EUH#TRPBF is a high-performance dual step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 60V and features two independent output channels. The device supports adjustable switching frequencies between 105kHz and 835kHz for the first channel, and 350kHz to 535kHz for the second channel. It utilizes a 32-WFQFN (5x5) package with an exposed pad and is rated for junction temperatures from -40°C to 125°C.
