LTC3775IMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3775IMSE#TRPBF is a synchronous step-down DC/DC switching controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 38V and supports adjustable switching frequencies from 250kHz to 1MHz. The device features a maximum duty cycle of 90% and includes integrated clock synchronization capabilities. Designed for surface-mount installation, it utilizes a 16-MSOP-EP package with an exposed pad for thermal management. The controller provides positive output configuration and incorporates control characteristics such as current limiting, enable functionality, frequency control, and soft start.

DC DC Switching Controllers Feature Summary

• Supports synchronous rectification for improved efficiency in buck converter applications
• Features integrated clock synchronization for noise reduction and multi-phase operation
• Includes comprehensive protection and control features like current limiting and soft start

DC DC Switching Controllers Applications

• Point-of-load regulation for industrial equipment
• Power distribution systems requiring isolated or non-isolated buck conversion
• Embedded systems with input voltages between 4.5V and 38V

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the 16-MSOP-EP package footprint matches your PCB design requirements. Ensure compatibility with the required switching frequency range and input voltage specifications for your application. Check for any recent product change notices regarding epoxy or marking changes.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a synchronous buck controller with clock synchronization. It is suitable for designs needing a wide input voltage range up to 38V. Consider the 16-MSOP-EP package size for space-constrained layouts. Verify that the external components support the desired switching frequency and current levels.
