LT8210EFE#PBF

Overview

The LT8210EFE#PBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices, designed for high-voltage applications with input and output voltages up to 100V. It supports pass-thru operation, forced continuous conduction, pulse-skipping, and Burst Mode. The device operates within an input voltage range of 2.8V to 100V, delivering up to 2.5A output current. Key electrical parameters include a switching frequency of 400kHz, quiescent current of 4uA, and load regulation of 1.8%. It functions in temperatures from -40°C to +125°C and is housed in a QFN-40 package.

Feature Summary

• Supports four distinct operational modes including pass-thru, forced continuous, pulse-skipping, and Burst Mode for optimized efficiency across varying load conditions.
• Capable of handling high voltage inputs and outputs up to 100V, suitable for demanding power management scenarios.
• Features low quiescent current consumption to enhance system efficiency during standby or light-load periods.

Applications

• High-voltage battery-powered systems requiring efficient step-up and step-down conversion
• Industrial equipment with wide input voltage ranges
• Automotive electronics operating under variable supply conditions

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm that the QFN-40 package type matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for Analog Devices components. Check for any recent Product Change Notifications (PCN) that might affect material composition or manufacturing location. Validate that the component is sourced from authorized distributors to guarantee authenticity and performance reliability.

Selection Notes

Select this controller when application requires handling input voltages up to 100V with synchronous buck-boost topology. Consider its 400kHz switching frequency for balancing size and efficiency. Evaluate the need for pass-thru mode functionality to minimize dropout voltage effects. Assess thermal management needs given the 125°C maximum operating temperature rating. Compare against alternatives if lower quiescent current or different package options are required.

Part Context

The LT8210EFE#PBF belongs to the LT8210 series of power management ICs by Analog Devices. It is part of a family of high-voltage synchronous buck-boost controllers designed for robust performance in challenging environments. This specific variant uses the EJE package code, indicating a QFN-40 form factor. It complements other LT8210 variants like LT8210EUJ#PBF which share similar electrical characteristics but may differ in package or suffix specifications.

Replacement Considerations

LT8210EUJ#PBF shares identical electrical specifications and functionality. Verify package compatibility between QFN-40 variants before substitution. Ensure pinout alignment remains consistent across both part numbers to avoid PCB redesign requirements.
