LTC3864IDE#TRPBF

DC DC Switching Controllers Overview

The LTC3864IDE#TRPBF is a synchronous step-down DC/DC switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 60V and supports adjustable switching frequencies from 50kHz to 850kHz. The device features a 12-DFN (4x3) package with an exposed pad for thermal management. It provides a single positive output configuration with integrated current limit, enable, frequency control, power good, and soft-start functionalities.

DC DC Switching Controllers Feature Summary

• Supports high input voltages up to 60V for flexible power distribution architectures
• Integrates comprehensive protection and control features including current limiting and soft-start
• Offers wide switching frequency adjustability to optimize external component size and efficiency

DC DC Switching Controllers Applications

• Industrial point-of-load regulation
• Telecommunications power systems
• Automotive electronics requiring robust voltage conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDE variant temperature range matches application requirements. Check manufacturer documentation for latest assembly drawings and RoHS compliance status prior to final design approval.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high input voltage tolerance and precise current mode control. Ensure the chosen inductor and capacitors support the selected switching frequency within the 50kHz to 850kHz range. Evaluate thermal performance based on the 12-DFN package dissipation capabilities under expected load conditions.

DC DC Switching Controllers Part Context

This component belongs to the LTC3864 family of synchronous buck controllers. It shares core architecture with other variants like the LTC3864HMSE but differs in package type and temperature rating. The family is designed for efficient voltage regulation in space-constrained industrial and commercial applications.

DC DC Switching Controllers Replacement Considerations

Direct pin-compatible alternatives within the same family include the LTC3864HMSE#PBF for MSOP packaging or the LTC3864EUFD#PBF for QFN options. Verify that any substitute maintains the required 60V input rating and switching frequency range.
