LT3663IMS8E#TRPBF

Overview

The LT3663IMS8E#TRPBF is a current mode step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7 V to 36 V and delivers up to 1.2 A of output current. The device features an adjustable output voltage and a fixed switching frequency of 1.5 MHz. It includes programmable output current limiting for system power dissipation control. The component supports shutdown functionality and functions within an operating temperature range of -40°C to +125°C. It is housed in an MSOP-8 package.

Feature Summary

• Current mode step-down topology with programmable output current limit
• Integrated high-side MOSFET supporting wide input voltage range
• Shutdown pin for low quiescent current operation
• Compact MSOP-8 surface mount package

Applications

• Battery-powered systems requiring efficient voltage regulation
• Industrial equipment power distribution networks
• Automotive electronics subsystems
• Portable instrumentation power supplies

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct electrical characteristics and package type. Check RoHS compliance status through official documentation before integration. Validate that the supplier provides genuine components from authorized channels to avoid counterfeit risks.

Selection Notes

Select this component when a buck converter with integrated switch and precise current limiting is required. The 1.5 MHz frequency allows for smaller passive components compared to lower frequency alternatives. Ensure the input voltage stays within the 7 V to 36 V range. Consider thermal performance in the MSOP-8 package for high load applications.

Part Context

This part belongs to the LT3663 family of synchronous buck regulators. It shares the core architecture with variants like LT3663EMS8E but differs in packaging and temperature grade specifications. The IMS8E designation typically denotes industrial temperature range performance in an MSOP-8 package.

Replacement Considerations

LT3663IMS8E#PBF offers identical electrical specifications but uses tube packaging instead of tape and reel.
