LTC3865EFE#PBF

DC DC Switching Controllers Overview

The LTC3865EFE#PBF is a synchronous dual step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 38 V and delivers up to 25 A per output channel across two independent outputs. The device supports adjustable output voltages from 600 mV to 5 V with a typical load regulation of 0.01%. Operating at a fixed switching frequency of 770 kHz, it features a quiescent current of 30 uA and functions reliably between -40°C and +125°C. Packaged in a TSSOP-EP-38 surface-mount format, the controller integrates shutdown capabilities and requires a 3 mA operating supply current.
