LT1946EMS8E#TRPBF

Overview

The LT1946EMS8E#TRPBF is a boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.45 V to 16 V and delivers up to 1.5 A output current. The device features a fixed switching frequency of 1.2 MHz and supports a maximum output voltage of 34 V. Packaged in an 8-lead MSOP-EP, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated 1.5 A power switch for high-current capability
• Fixed 1.2 MHz switching frequency minimizes external component size
• Shutdown pin enables low quiescent current operation

Applications

• Battery-powered portable equipment
• Industrial control systems
• Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging. Confirm the manufacturer part number matches Analog Devices documentation exactly. Check RoHS compliance status via official datasheets. Ensure the MSOP-8 package variant aligns with PCB footprint requirements before ordering.

Selection Notes

Select this component when a compact boost solution is required for inputs between 2.45 V and 16 V. The fixed 1.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 1.5 A switch current rating meets peak load demands without exceeding thermal limits in the MSOP-8EP package.

Part Context

This part belongs to the LT1946 family of boost converters designed for space-constrained applications. It integrates a synchronous rectifier and power switch to maximize efficiency. The MSOP-8EP package provides thermal performance suitable for moderate power densities in portable devices.

Replacement Considerations

LT1946EMS8E#PBF offers identical electrical specifications but utilizes tube packaging instead of tape and reel.
