LTC3864HMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3864HMSE#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 output voltages from 800mV to the input voltage. The device features a switching frequency adjustable between 50kHz and 850kHz, housed in a 12-MSOP-EP package. It provides current mode control with cycle-by-cycle current limiting, soft start, and power good indication.

DC DC Switching Controllers Feature Summary

• Supports high input voltages up to 60V for flexible power distribution
• Adjustable switching frequency allows optimization for size and efficiency
• Integrated cycle-by-cycle current limiting protects against overload conditions

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Power management for telecom infrastructure
• Embedded systems requiring isolated or non-isolated buck conversion

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Check for recent manufacturing changes such as epoxy or bond wire updates. Ensure ESD handling procedures are followed during assembly. Validate package marking against datasheet specifications.

DC DC Switching Controllers Selection Notes

Select this controller when high input voltage capability is required. Consider thermal performance due to MSOP-EP package constraints. Evaluate external MOSFET selection for optimal efficiency at target frequencies. Verify compatibility with system timing requirements and loop stability needs.

DC DC Switching Controllers Part Context

Part of the LTC3864 family offering synchronous buck control. Shares core architecture with LTC3863 but differs in pinout and feature set. Designed for applications requiring precise voltage regulation under varying load conditions. Compatible with standard LTpowerCAD design tools for simulation.

DC DC Switching Controllers Replacement Considerations

LTC3864IMSE#PBF offers identical functionality in tube packaging. LTC3864IDE#PBF provides DFN package alternative for different board layouts. Cross-reference with LTC3863 only if pin compatibility and feature overlap are confirmed.
