LTC3864EDE#PBF

DC DC Switching Controllers Overview

The LTC3864EDE#PBF 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 maximum duty cycle of 100% and provides current limit, enable, frequency control, power good, and soft-start capabilities. It is housed in a 12-MSOP-EP package and functions within a junction temperature range of -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Supports 100% duty cycle operation for minimal dropout voltage applications
• Integrated power good signal for system monitoring
• Programmable switching frequency ranging from 50kHz to 850kHz
• Includes soft-start functionality to limit inrush current

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Power distribution systems requiring wide input voltage ranges
• Embedded computing platforms needing efficient step-down conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and tape/reel or tube packaging configuration against the manufacturer's latest documentation before ordering. Confirm that the 12-MSOP-EP footprint matches the design board layout. Ensure the operating temperature requirements align with the specified -40°C to 125°C junction range for the intended environment.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside programmable frequency control. The 100% duty cycle capability makes it suitable for low output voltage applications where standard controllers may fail to regulate. Consider the thermal performance of the MSOP-EP package for heat dissipation needs in the final assembly.

DC DC Switching Controllers Part Context

This part belongs to the LTC3864 family of synchronous buck controllers designed for high-efficiency power management. It complements other PMIC solutions by offering robust protection features and precise control loops. The device is intended for designers seeking reliable step-down conversion in compact form factors without sacrificing input voltage flexibility.

DC DC Switching Controllers Replacement Considerations

Direct replacements include other LTC3864 variants with different temperature grades or package options, such as the LTC3864IMSE#PBF. Verify pin compatibility and electrical specifications before substituting.
