LT3663IMS8E-3.3#PBF

Overview

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

Feature Summary

Current mode control architecture for stable regulation
Programmable output current limit to manage system power dissipation
Automotive-grade reliability for harsh environments

Applications

Automotive electronics systems
Industrial DC-DC conversion
Distributed power architectures

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the automotive grade designation matches project requirements. Ensure the fixed 3.3 V output aligns with load specifications. Cross-reference the MSOP-8 package dimensions with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a robust buck converter with integrated current limiting. The fixed 3.3 V output simplifies design compared to adjustable variants. Consider the 1.1 MHz frequency for balancing efficiency and external component size. Verify thermal performance under maximum load conditions within the specified operating temperature range.

Part Context

This part belongs to the LT3663 family of high-efficiency synchronous buck regulators. The series is designed for space-constrained applications requiring reliable power delivery. The IMS8E variant denotes the industrial/automotive temperature range and MSOP-8 package style, distinguishing it from other pinouts or grades in the lineup.
