LT3663EDCB-5#TRMPBF

Overview

The LT3663EDCB-5#TRMPBF is a current mode step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7.5V to 36V and provides a fixed output voltage of 5V at up to 1.2A. The device features a programmable output current limit for accurate system power dissipation control. It utilizes an 8-pin DFN EP package and is qualified for automotive applications.

Feature Summary

Current mode buck topology with integrated 1.2A switch
Programmable output current limit for thermal management
Automotive grade qualification

Applications

2.5V or 5V step-down converter circuits
Automotive power distribution systems
Industrial battery charger applications

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging and lead-free status. Confirm automotive AEC-Q100 compliance if required for your design. Check current availability as stock may be limited. Ensure the 8-pin DFN EP footprint matches your PCB layout constraints before ordering.

Selection Notes

Select this component when a robust, automotive-grade buck regulator is needed for high-voltage inputs up to 36V. The fixed 5V output simplifies design compared to adjustable variants. Consider the programmable current limit feature if precise power path protection is necessary without external sensing components.

Part Context

This part belongs to the LT3663 family of high voltage synchronous buck regulators. It shares architectural similarities with other LT36xx series devices but offers specific fixed output voltages and automotive reliability standards. The DFN EP package provides efficient thermal performance for compact designs.
