LTC3892MPUH-2#PBF

DC DC Switching Controllers Overview

The LTC3892MPUH-2#PBF is a high-performance dual step-down DC/DC switching regulator controller from Analog Devices. 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. It features low quiescent current for efficient standby operation. The component is housed in a 32-lead QFN package suitable for surface mount applications.
