LTC3863HMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3863HMSE#TRPBF is a DC/DC switching controller manufactured by Analog Devices Inc., designed for buck and inverting topologies. It operates with an input voltage range of 3.5V to 60V and supports adjustable switching frequencies from 50kHz to 850kHz. The device provides one output channel with positive or negative output configuration options. It features current limit, enable, frequency control, and soft start capabilities. The component is housed in a 12-MSOP-EP package and functions within a junction temperature range of -40°C to 150°C.

DC DC Switching Controllers Feature Summary

• Supports both step-down (buck) and inverting DC/DC converter topologies
• Includes integrated soft start and cycle-by-cycle current limiting protection
• Allows external synchronization via adjustable switching frequency control
• Operates with high input voltage ranges up to 60V

DC DC Switching Controllers Applications

• Industrial power supply systems requiring isolated or non-isolated regulation
• Telecommunications equipment utilizing wide input voltage rails
• Embedded systems converting higher bus voltages to lower logic levels
• Inverting power architectures generating negative rail supplies

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 thermal performance specifications. Ensure compatibility with the 12-MSOP-EP footprint during PCB layout. Cross-reference official datasheets for any recent manufacturing changes or PCN updates affecting material composition.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring flexible topology support between buck and inverting configurations. Consider the wide operating temperature range for harsh environment applications. Evaluate the need for external MOSFETs as this is a controller without integrated power switches. Verify that the required switching frequency falls within the 50kHz to 850kHz operational window.
