LTC3869IUFD#TRPBF

DC DC Switching Controllers Overview

The LTC3869IUFD#TRPBF is a dual synchronous buck DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 60V and supports output voltages from 800mV to 24V. The device features two phases with 180-degree phase shifting to minimize input capacitance requirements. It utilizes current mode control with accurate multiphase current matching via external sense resistors. The controller is housed in a 28-lead QFN package (4x5mm) and is designed for high-efficiency power conversion applications.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture with 180-degree phase shifting to reduce input ripple and noise
• Accurate multiphase current sharing using external sense resistors
• Wide input voltage capability supporting up to 60V sources
• Integrated synchronous rectification control for high efficiency

DC DC Switching Controllers Applications

• High-density point-of-load regulation
• Industrial equipment power supplies
• Telecommunications infrastructure
• Server and storage systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check RoHS compliance status through official datasheets or distributor documentation before integration into regulated products.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring wide input voltage ranges up to 60V. The dual-phase topology is suitable for reducing input capacitor count. Ensure external components support the required switching frequency and current levels. Verify thermal performance within the QFN-28 package constraints for the target application load.

DC DC Switching Controllers Part Context

This part belongs to the LTC3869 family of synchronous buck controllers. It is distinct from single-phase variants and higher-pin-count models. The #TRPBF suffix denotes the specific reel packaging format, while the base model defines the electrical characteristics and pinout configuration.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other Analog Devices dual buck controllers such as the LTC3890 series for similar voltage ranges. Verify pin compatibility and control loop stability when cross-referencing with competitors like Texas Instruments or Infineon equivalents.
