LT8390AIFE#TRPBF

Overview

The LT8390AIFE#TRPBF is a synchronous buck-boost DC/DC controller from Analog Devices, housed in a TSSOP-EP-28 package. It supports an input voltage range of 4 V to 60 V and delivers an output voltage of 0 V to 60 V with a single output channel. The device operates at a switching frequency between 600 kHz and 2 MHz, featuring a quiescent current of 2.1 mA and load regulation of 1%. It functions within a temperature range of -40°C to +125°C.

Feature Summary

Synchronous four-switch buck-boost topology for flexible voltage conversion
Integrated soft-start functionality to manage inrush currents
Wide operating input and output voltage ranges up to 60 V

Applications

Industrial power supply systems
Distributed power architectures
Battery-powered equipment requiring wide input ranges

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability data. Cross-reference the manufacturer part number against authorized distributor lists to avoid counterfeit components. Validate that the component matches the specified A-grade temperature rating.

Selection Notes

Select this controller for applications requiring both buck and boost capabilities within a single stage. The wide input voltage range suits systems with varying source conditions. Consider the thermal performance of the exposed pad package for heat dissipation. Evaluate the 2 MHz maximum frequency for trade-offs between component size and efficiency. Ensure external MOSFETs support the required voltage and current ratings.

Part Context
