LT3663EDCB#TRPBF

Overview

The LT3663EDCB#TRPBF 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 utilizes a 8-pin DFN EP package and supports automotive applications. Key electrical parameters include a switching frequency of 1.5MHz, an operating temperature range from -40°C to +125°C, and integrated soft-start functionality.

Feature Summary

Integrates programmable output current limit for accurate system power dissipation control
Utilizes current mode architecture for stable regulation
Features integrated soft-start to manage inrush current during startup

Applications

Automotive power distribution systems
Industrial point-of-load conversion
General DC-DC step-down power supplies

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the ED variant meets required automotive qualification standards if applicable. Ensure compatibility with the 8-pin DFN EP footprint during PCB layout. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high input voltage tolerance up to 36V. The fixed 5V output simplifies design for standard logic rails. Consider the 1.2A current capability against peak load requirements. The compact DFN package suits space-constrained layouts. Verify thermal performance under maximum load conditions within the specified temperature range.

Part Context

This part belongs to the LT3663 family of synchronous buck regulators. It shares architectural similarities with other high-voltage step-down converters but offers a fixed 5V output option. The device is designed to replace linear regulators in higher voltage applications to improve efficiency. It complements Analog Devices' portfolio of automotive-grade power management solutions.
