LT3990EMSE-5#TRPBF

Overview

The LT3990EMSE-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It features an adjustable frequency range from 210kHz to 2.3MHz and accepts input voltages up to 62V. The device provides a fixed 5V output with a maximum current of 350mA. It operates within a temperature range of -40°C to 125°C TJ. The component utilizes a 16-TFSOP package with an exposed pad for thermal management.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size
Wide input voltage range supports diverse power supply architectures
Low quiescent current enhances battery life in portable applications

Applications

Industrial control systems requiring stable 5V rails
Embedded computing platforms with high-voltage inputs
Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the 16-MSOP-EP package type aligns with your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when a fixed 5V output is required without external feedback resistors. The wide input range makes it suitable for bus voltage conversion. Consider the thermal performance of the exposed pad package for heat dissipation requirements. Verify that the 350mA output current meets the load demands of the target circuit application.

Part Context

This part belongs to the LT3990 family of high-voltage buck regulators. It shares core architecture with other variants like LT3990EMSE-3.3 but differs in fixed output voltage. The EMSE designation indicates the specific MSOP package and temperature grade. The #TRPBF suffix denotes lead-free tape and reel packaging for automated assembly.
