LT3663IMS8E-3.3#TRPBF

Overview

The LT3663IMS8E-3.3#TRPBF is a current mode step-down switching regulator manufactured by Analog Devices Inc. It features a fixed 3.3V output and supports a maximum output current of 1.2A. The device operates with an input voltage range from 7.5V to 36V and utilizes a 1.1MHz switching frequency. Packaged in an 8-pin MSOP with exposed pad, it functions within an extended temperature range of -40°C to +125°C.

Feature Summary

Integrates programmable output current limit for precise system power dissipation control
Utilizes current mode architecture to reduce power path component size
Supports automotive grade operation with extended temperature capabilities

Applications

3.3V Step-Down Converter designs
Automotive power management systems
Systems requiring precise current limiting

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any specific automotive qualification certifications if required for the target application environment.

Selection Notes

Select this component for applications requiring a fixed 3.3V output from higher input voltages up to 36V. The 1.2A current capability suits moderate load requirements. Consider the 8-pin MSOP package constraints for thermal management. Verify that the 1.1MHz frequency aligns with EMI constraints and inductor selection guidelines for the specific design.

Part Context

This part belongs to the LT3663 series of current mode buck regulators. It shares architectural similarities with other variants like the adjustable LT3663IMS8E but provides a fixed internal feedback network for 3.3V output. The series emphasizes compact solution sizes through high-frequency operation and integrated current limiting features.
