LT3154AV#PBF

Overview

The LT3154AV#PBF is a synchronous buck-boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1.8 V to 5.5 V and delivers up to 5 A of output current. The device supports adjustable output voltages from 1.8 V to 5.5 V. Key electrical specifications include a quiescent current of 17 uA, a switching frequency of 2.2 MHz, and operation across a temperature range of -40°C to +125°C. It utilizes a 16-pin LQFN package.

Feature Summary

Synchronous buck-boost topology supporting wide input and output voltage ranges
Integrated shutdown control for power management
High efficiency operation at 2.2 MHz switching frequency

Applications

Battery-powered portable electronics
Industrial sensor nodes
IoT devices requiring stable regulation from varying supply sources

Procurement Notes

Verify the suffix #PBF indicates tube packaging rather than tape and reel. Confirm the AV grade matches required temperature and performance specifications. Cross-reference the specific datasheet revision for pinout and thermal pad details. Ensure compatibility with the intended PCB footprint for the LQFN-16 package before finalizing procurement orders.

Selection Notes

Select this component when input voltage may rise above or fall below the desired output voltage. The 5 A capability suits high-current loads in compact spaces. Compare against the TRPBF variant if reel packaging is preferred for automated assembly. Evaluate thermal requirements based on the LQFN-16 package size and expected load conditions.

Part Context

This part belongs to the LT3154 series of synchronous buck-boost converters. It shares functional similarities with other ADI PMICs but is distinct in its 5 A current rating and specific 1.8 V to 5.5 V operating window. The series targets applications needing robust regulation from single-cell lithium batteries or similar variable sources.
