LTC3894EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3894EFE#TRPBF is a synchronous step-down switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 6V to 150V and provides a single non-isolated output. The device supports a fixed switching frequency of 150kHz and delivers up to 3A of output current. It utilizes a 20-TSSOP-EP package and is designed for high-voltage DC/DC conversion applications.

DC DC Switching Controllers Feature Summary

• Supports wide input voltage ranges up to 150V
• Synchronous buck topology for high efficiency
• Fixed 150kHz switching frequency operation

DC DC Switching Controllers Applications

• High-voltage industrial power supplies
• Telecommunications equipment
• Distributed power systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure compatibility with evaluation boards like the DC2506A. Check official distributor listings for current availability status as supply levels may vary.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring high input voltages with moderate output current. Ensure the thermal design accommodates the TSSOP-EP package constraints. Verify that the required output voltage falls within the controller's adjustable range and that the load does not exceed the 3A limit specified in the datasheet.

DC DC Switching Controllers Part Context

This controller belongs to the LTC3894 family, which includes variants such as the EFE and IFE packages. It is distinct from lower voltage controllers like the LTC3891 or multi-phase devices like the LTC3890. The part is often evaluated using the dedicated DC2506A demonstration circuit board provided by Analog Devices.
