LT3845MPFE#PBF

Overview

The LT3845MPFE#PBF is a high voltage synchronous current mode step-down controller manufactured by Analog Devices Inc. It operates within an input voltage range of 7.5 V to 60 V and supports up to 10 A output current. The device features an adjustable switching frequency from 100 kHz to 500 kHz and maintains a quiescent current of 120 uA. Designed for TSSOP-16 surface mount packages, it functions reliably across temperatures ranging from -55 °C to +125 °C.

Feature Summary

• Synchronous current mode control architecture for medium to high power applications
• Adjustable operating frequency with synchronization capability
• Integrated soft-start functionality to manage startup transients

Applications

• Industrial control systems
