LT3663HMS8E#TRPBF

Overview

The LT3663HMS8E#TRPBF is a current mode step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7V to 36V and delivers a maximum output current of 1.2A. The device features a fixed switching frequency of 1.5MHz and supports adjustable output voltage configurations. It functions within an extended temperature range from -40°C to +150°C, utilizing an MSOP-8 package with exposed pad for surface mount installation.

Feature Summary

Current mode control architecture with programmable output current limit
Extended thermal performance supporting operation up to 150°C
Integrated shutdown capability for power management

Applications

Automotive electronics systems
Industrial power distribution networks
Point-of-load regulation in compact designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as Analog Devices Inc. or Linear Technology to ensure authenticity. Check for RoHS compliance documentation relevant to the production batch. Ensure the MSOP-8 package type matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high efficiency buck conversion within a wide input voltage window. The 1.5MHz switching frequency allows for smaller passive components compared to lower frequency alternatives. Consider the 150°C operating limit for environments with elevated ambient temperatures. Verify that the 1.2A output current meets the load requirements without exceeding thermal constraints.

Part Context

This part belongs to the LT3663 family of synchronous step-down converters designed for automotive and industrial use. It shares architectural similarities with other members like the LT3663EMS8E-3.3 but differs in package and specific electrical characteristics. The series emphasizes compact size and robust performance under varying load conditions.
