DC DC Switching Controllers datasheet and documents for LTC3894HFE#TRPBF

LTC3894HFE#TRPBF

DC DC Switching Controllers Overview

The LTC3894HFE#TRPBF is a high-voltage synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It supports an input voltage range of 4.5V to 150V and delivers up to 10A output current with adjustable output voltages from 1.2V to 150V. The device operates at a fixed switching frequency of 600kHz and features a maximum duty cycle of 90%. It is housed in a 38-lead TSSOP package with an exposed pad, designed for surface mount installation. The component functions within a junction temperature range of -40°C to +150°C.

DC DC Switching Controllers Feature Summary

Capable of handling high input voltages up to 150V for industrial applications
Supports single-output synchronous buck topology with integrated low-side drive
Includes protection features such as thermal shutdown and current limit

DC DC Switching Controllers Applications

Industrial power supplies
Telecommunications equipment
Automotive systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the H-grade designation matches required operating temperature ranges for your application environment. Ensure compatibility with the 38-lead TSSOP footprint during PCB layout finalization.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring wide input voltage ranges exceeding standard 60V limits. Consider the 600kHz switching frequency for balancing efficiency and passive component size. Verify that the external MOSFETs can handle the 10A current capability and 150V blocking voltage requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3894 family of high-voltage synchronous step-down controllers. It shares functional similarities with other Linear Technology parts like the LTC3779 but is optimized for buck topologies rather than buck-boost configurations. The series targets robust power management in demanding environments.
