LTC3865IFE#PBF

DC DC Switching Controllers Overview

The LTC3865IFE#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 38 V and provides two independent outputs adjustable from 600 mV to 5 V. The device supports output currents up to 25 A per channel with a fixed switching frequency of 770 kHz. It features pin-selectable output configurations, shutdown capability, and a load regulation of 0.01%. Designed for high efficiency, it functions within a temperature range of -40°C to +125°C and utilizes a 38-lead TSSOP-EP package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package type against official Analog Devices documentation to ensure compatibility with your circuit design. Confirm that the component meets all required environmental and safety standards for your intended application before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated or non-isolated low-voltage rails are required from a higher voltage bus. Ensure the external inductor and capacitor values support the 25 A current requirement at the chosen operating frequency. Verify thermal management capabilities for the TSSOP-EP package under maximum load conditions.

DC DC Switching Controllers Part Context

This component belongs to the LTC3865 family of dual synchronous DC/DC controllers. It shares core functionality with variants like the LTC3865IUH-1#PBF but differs in package style. The series is designed for applications requiring high efficiency and compact footprint in power management solutions.

DC DC Switching Controllers Replacement Considerations

Direct replacements include other members of the LTC3865 family such as the LTC3865IUH-1#PBF. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit and electrical performance remain consistent.
