LTC3892IUH#TRPBF

DC DC Switching Controllers Overview

The LTC3892IUH#TRPBF is a high-performance dual step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It drives all N-channel synchronous power MOSFET stages to minimize power loss and noise through out-of-phase operation of the two controller output stages. The device supports an input voltage range of 4.5V to 60V and features a switch frequency adjustable from 105kHz to 835kHz, with a secondary range of 350kHz to 535kHz. It operates within a junction temperature range of -40°C to 125°C and is housed in a 32-WFQFN (5x5) package.
