LTC3894IFE#PBF

DC DC Switching Controllers Overview

The LTC3894IFE#PBF is a synchronous step-down switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 60V and supports output voltages from 800mV to 24V. The device features a fixed switching frequency of 150kHz, though it can be synchronized to an external clock. It utilizes a constant frequency current mode architecture for precise regulation. The component is housed in a 20-lead TSSOP package with an exposed pad (TSSOP-EP) and is rated for operation within a temperature range of -40°C to +125°C.
