Overview
The LT8210IFE#PBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices Inc. It supports an input voltage range of 2.8V to 100V and delivers up to 2.5A output current. The device features adjustable switching frequencies between 80kHz and 400kHz, with a typical quiescent current of 4µA. It operates within a temperature range of -40°C to 125°C and is housed in a 38-lead TSSOP-EP package.
Feature Summary
- Supports passthru operation for high efficiency near unity gain
- Offers multiple operating modes including forced continuous, pulse-skipping, and Burst Mode
- Integrates a 4-switch synchronous topology for versatile step-up and step-down regulation
Applications
- Battery-powered systems requiring wide input voltage ranges
- Industrial control applications with varying supply conditions
- Automotive electronics utilizing 12V or 24V battery architectures
Procurement Notes
Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the 38-TSSOP-EP package type matches your PCB footprint requirements. Ensure the 100V rating aligns with your system's maximum transient voltage specifications before finalizing procurement.
Selection Notes
Select this component for designs requiring a single inductor solution across wide input-output differentials. Consider the 4-switch topology for improved efficiency compared to standard buck-boost converters. Evaluate the thermal performance of the exposed pad package against your board's heat dissipation capabilities.
Part Context
This part belongs to the LT8210 family of high-voltage controllers. It complements other Analog Devices power management solutions by providing robust buck-boost functionality. The device is designed to replace discrete switch implementations, simplifying circuit design while maintaining high reliability in demanding environments.
Replacement Considerations
The LT8210EUJ#PBF serves as a pin-compatible alternative in the QFN-40 package. Verify that the package dimension changes do not impact your existing layout constraints when considering substitution.
