LT8210EUJ#TRPBF

Overview

The LT8210EUJ#TRPBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices. It supports input voltages from 2.8V to 100V and delivers up to 2.5A output current with a single output channel. The device operates at a switching frequency of 400kHz and features a quiescent current of 4µA. It accommodates output voltages ranging from 1V to 100V, with a load regulation of 1.8%. The component functions within a temperature range of -40°C to +125°C and is housed in a QFN-40 package.

Feature Summary

• Supports passthru, forced continuous, pulse-skipping, and Burst Mode operation for optimized efficiency across varying load conditions.

Applications

• Industrial power systems requiring wide input voltage ranges
• Battery-powered equipment utilizing pass-through functionality
• Automotive electronics operating under variable supply conditions

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from the tube variant. Confirm availability status as distribution channels may report limited stock or restricted supply. Ensure the QFN-40 footprint matches the design layout before finalizing procurement orders.

Selection Notes

Select this controller when designing circuits requiring a wide input voltage window up to 100V. Consider the 4-switch topology for efficient buck-boost conversion. Evaluate the need for passthru mode to maintain direct input-to-output transfer during specific voltage windows.

Part Context

This component belongs to the LT8210 series of power management ICs. It serves as a high-voltage synchronous buck-boost controller designed for applications demanding flexible voltage conversion capabilities. The series emphasizes efficiency through multiple operational modes.

Replacement Considerations

LT8210EUJ#PBF is a verified substitute part number representing the same functional device in tube packaging rather than tape-and-reel.
