LTC3853IUJ#TRPBF Description

Short technical summary and product information.

The LTC3853IUJ#PBF from Analog Devices Inc. is a triple output buck DC-DC controller designed for efficient power conversion. It supports positive step-down outputs and utilizes a transistor driver output. The controller is housed in a compact 40-pin QFN package (6x6mm), making it suitable for high-performance applications requiring multiple regulation channels.

 

Key electrical specifications include an input voltage range of 4.5V to 24V, a switching frequency adjustable from 250kHz to 750kHz, and a maximum duty cycle of 98%. It features synchronous rectification for improved efficiency and includes advanced control functions such as current limit, enable, frequency control, power good, soft start, and tracking.

 

The device operates within a temperature range of -40°C to 125°C and is designed for surface-mount applications. It is built into a 40-WFQFN exposed pad package. The controller does not have a built-in clock sync or serial interface, but its outputs use transistor drivers.

 

This controller is suitable for industrial systems, telecom equipment, networking devices, server motherboards, and advanced embedded platforms. It is designed for environments needing stable multi-rail power at varying voltages and temperatures, offering reliable operation under harsh conditions.
