LT8609AHMSE#PBF

Overview

The LT8609AHMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and provides a continuous output current of 2 A, with a peak capability of 3 A. The device features a switch frequency range from 200 kHz to 2.2 MHz and delivers an adjustable output voltage. It utilizes an MSOP-16 package and maintains a low non-switching quiescent current of 1.7 uA. The component supports operation across a temperature range of -40°C to +150°C junction temperature.

Feature Summary

• Synchronous buck topology for high efficiency
• Wide 42V input voltage range
• Low quiescent current consumption

Applications
