LT8392JUFD#TRPBF

Overview

The LT8392JUFD#TRPBF is a synchronous four-switch buck-boost DC/DC controller from Analog Devices. It operates with an input voltage range of 4V to 60V and supports output voltages up to 60V. The device integrates a fixed switching frequency of 420kHz, selectable via an external resistor. It features a low quiescent current of 150µA and supports operation in both continuous and discontinuous conduction modes. The component is housed in a 28-pin QFN package with exposed pad for thermal management.

Feature Summary

Synchronous four-switch topology enabling efficient buck, boost, and buck-boost regulation
Integrated current mode control for precise input and output current regulation
Wide input voltage range supporting diverse power source conditions
Low quiescent current design optimizing standby power consumption

Applications

Industrial motor drives requiring wide input voltage ranges
Battery-powered systems with varying cell counts
Automotive infotainment and lighting controllers
PoE (Power over Ethernet) interface circuits

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the JUFD designation corresponds to the 28-pin QFN package variant. Ensure compatibility with the intended switching frequency configuration before procurement. Check for RoHS compliance documentation as required by project specifications.

Selection Notes

Select this controller for applications demanding high efficiency across wide input-output voltage differentials. Consider the 420kHz fixed frequency for EMI filtering requirements. Evaluate thermal performance due to the integrated synchronous switches. Verify that the 60V rating aligns with peak transient voltages in the target system.

Part Context

This component belongs to the LT8392 family of synchronous buck-boost controllers. It shares functional similarities with the LT8390 but offers distinct pinout and package options. The JUFD suffix specifically denotes the QFN package variant, differing from the TSSOP option found in other series members like the LT8390JFE.
