LT8392EUFD#TRPBF

Overview

The LT8392EUFD#TRPBF is a synchronous four-switch buck-boost DC/DC controller from Analog Devices. It supports an input voltage range of 3V to 60V and provides a positive output. The device operates with a fixed switching frequency of 400kHz and incorporates spread spectrum technology to reduce EMI. It features a 28-pin QFN package (4x5mm) with exposed pad for thermal management. The controller includes integrated soft-start, current limit protection, and power good indication. It is designed for applications requiring wide input/output voltage ranges and high efficiency across varying load conditions.

Feature Summary

Synchronous four-switch buck-boost topology for efficient step-up and step-down conversion
Integrated spread spectrum modulation to minimize electromagnetic interference
Wide input voltage range supporting 3V to 60V operation
Built-in protection features including soft-start and current limiting

Applications

Industrial automation power supplies
Battery-powered equipment with wide voltage variation
LED lighting drivers requiring constant current regulation
Telecommunications infrastructure power systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the 28-QFN package matches your PCB footprint requirements. Ensure the 400kHz switching frequency aligns with your EMI constraints and inductor selection. Check for any regional distribution restrictions or lead time variations before finalizing procurement plans.

Selection Notes

Select this component when a wide input voltage range up to 60V is required with both buck and boost capabilities. Consider the 400kHz fixed frequency for predictable filter design. Evaluate the QFN-28 package size against available board space. Compare against other LT839x variants if different switching frequencies or additional channels are needed for your system architecture.

Part Context

The LT8392 belongs to Analog Devices' LT839x family of synchronous buck-boost controllers. This series is designed for applications requiring flexible voltage conversion between input and output rails. The EUFD variant specifically denotes the 28-lead QFN package with exposed pad for enhanced thermal performance in compact designs.
