LT8392HFE#TRPBF

Overview

The LT8392HFE#TRPBF is a synchronous 4-switch buck-boost DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 60V and supports output voltages from 0V to 60V. The device features a fixed switching frequency of 600kHz and maintains a maximum quiescent current of 2.8mA. Designed for robust performance, it functions across an extended temperature range from -40°C to +150°C. The component is housed in a 28-TSSOP-EP package with an exposed pad for thermal management.

Feature Summary

Synchronous four-switch topology enabling regulation when input voltage is above, below, or equal to the output voltage
Integrated spread spectrum modulation to reduce electromagnetic interference peaks
Capable of regulating output voltage, input current, or output current modes

Applications

Industrial power supply systems requiring wide input voltage ranges
Battery-powered equipment utilizing lithium-ion or multi-cell battery configurations
Automotive electronics operating under varying load and source conditions
LED lighting drivers demanding stable current regulation across fluctuating inputs

Procurement Notes

Verify that the suffix TRPBF indicates tape-and-reel packaging rather than tube packaging. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides traceability data matching Analog Devices specifications. Validate the exposed pad thermal requirements against your PCB layout design before finalizing orders.

Selection Notes

Select this controller for applications requiring seamless transition between buck and boost modes without external component complexity. Consider the 600kHz fixed frequency for balancing efficiency and passive component size. Evaluate the TSSOP-28-EP package for its thermal dissipation capabilities in high-power density designs compared to standard packages.

Part Context

This part belongs to the LT8392 family of synchronous buck-boost controllers designed for high-efficiency power conversion. It shares architectural similarities with the LT8390 and LT8391 but offers specific control features tailored for versatile voltage regulation scenarios. The family targets industrial and automotive markets needing reliable power management solutions.
