LTC3864HDE#TRPBF

DC DC Switching Controllers Overview

The LTC3864HDE#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 60V and supports switching frequencies from 50kHz to 850kHz. The device features a 12-DFN (4x3) package and provides a single positive output configuration. It includes control characteristics such as current limit, enable, frequency control, power good, and soft start capabilities.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for high-efficiency power conversion
• Integrated current limit and soft start functionality
• Wide input voltage range supporting various bus voltages
• Programmable switching frequency for optimized design flexibility

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial systems
• Power distribution networks for embedded applications
• Telecommunications infrastructure equipment
• Automotive electronics requiring robust voltage regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm that the DFN-12 package matches your PCB footprint requirements. Ensure compatibility with the required operating temperature range of -40°C to 125°C. Check for any recent product change notifications regarding epoxy or marking changes that may affect assembly processes.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 60V is required for synchronous buck applications. Consider the 12-DFN package size for space-constrained designs. Evaluate the need for programmable frequency to minimize external component count. Compare against other LTC3864 variants if different package styles like MSOP are preferred for thermal or mechanical reasons.

DC DC Switching Controllers Part Context

This part belongs to the LTC3864 family of synchronous step-down controllers. It shares core electrical specifications with other variants in the series but differs primarily in package type and shipping format. The HDE suffix denotes the specific DFN-12 package configuration suitable for surface-mount assembly.

DC DC Switching Controllers Replacement Considerations

LTC3864HMSE#PBF offers identical electrical performance in a 12-MSOP-EP package. LTC3864IDE#PBF provides the same functionality in a tube-packaged 12-DFN variant. Verify pinout compatibility and thermal pad requirements before substituting.
