LTC3892HUH#PBF

DC DC Switching Controllers Overview

The LTC3892HUH#PBF is a high-performance dual step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 60 V and supports output voltages from 800 mV to 59.4 V. The device features a low quiescent current of 34 uA and adjustable switching frequencies between 105 kHz and 835 kHz. Packaged in a 32-WFQFN (5x5) housing, it provides two independent output channels capable of driving N-channel synchronous power MOSFETs. The controller includes integrated soft-start, tracking, and current limit functions for robust power management.
