LTC3851AEMSE-1 Description

Short technical summary and product information.

The LTC3851AEMSE-1 is a Synchronous Step-Down Switching Regulator Controller manufactured by Linear Technology (LT). This component is designed for efficient power management applications, featuring a wide input voltage range from 4V to 38V and supporting output voltages from 0.8V to 5.5V.

 

Key electrical specifications include a phase-lockable fixed frequency that can be set between 250kHz and 750kHz, with a typical maximum frequency of 750kHz. It offers ±1% output voltage accuracy and a very low dropout operation of 99% duty cycle. The controller also includes features like R SENSE or DCR current sensing, power good output voltage monitoring, adjustable output voltage soft-start or tracking, and output current foldback limiting.

 

Packaged in an MS-16E case, this surface-mount device is suitable for various electronic systems requiring robust DC/DC conversion. The operating temperature range is from 0°C to 85°C. The device also has a low shutdown current of 25µA, making it suitable for power-sensitive applications.
