LT8390JUFD#TRPBF

Overview

The LT8390JUFD#TRPBF is a synchronous four-switch buck-boost DC/DC controller from Analog Devices. It operates with an input voltage range of 4 V to 60 V and supports output voltages up to 60 V. The device utilizes proprietary peak-buck/peak-boost current mode control to regulate output voltage, input current, or output current regardless of whether the input voltage is above, below, or equal to the output voltage. It features a fixed switching frequency of 650 kHz and a shutdown pin for power management. The component is housed in a QFN-28 package and is designed for industrial applications requiring robust power conversion across wide voltage ranges.

Feature Summary

Synchronous four-switch topology enables efficient buck, boost, and pass-through operation
Proprietary peak-buck/peak-boost current mode control regulates voltage, input current, or output current
Integrated soft-start capability minimizes inrush current during startup

Applications

Industrial power supplies
Distributed power systems
Battery-powered equipment

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm that the specific revision matches your design requirements. Cross-reference the datasheet for any updates regarding recommended operating conditions or thermal performance data before finalizing procurement orders.

Selection Notes

Select this controller when input voltages vary significantly relative to the output voltage, such as in battery applications where voltage drops during discharge. The integrated current regulation modes allow for precise protection without external sensing complexity. Ensure the external components selected are rated for the maximum 60 V operating limits and the required current levels.

Part Context

This component belongs to the LT8390 family of high-voltage synchronous buck-boost controllers. It is distinct from standard buck or boost regulators by its ability to handle input voltages both higher and lower than the output. The JUFD suffix indicates a specific package variant within the broader LT8390 series, which also includes other package options like TSSOP.
