Overview
The LT8210IFE#TRPBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices. It supports an input voltage range of 2.8V to 100V and delivers up to 2.5A output current. The device operates with a switching frequency between 80kHz and 400kHz, featuring a typical quiescent current of 4µA. It offers one output channel with load regulation of 1.8%. The component functions in passthru, forced continuous, pulse-skipping, and Burst Mode. It is housed in a TSSOP-38 package and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Supports passthru operation when input voltage falls within a user-programmable window
- Enables direct transfer of input voltage to output for improved efficiency
- Operates in forced continuous, pulse-skipping, and Burst Mode for flexible control
Applications
- Industrial power supplies requiring wide input voltage ranges
- Battery-powered systems needing efficient buck-boost conversion
- Automotive electronics operating under varying line conditions
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm that the TSSOP-38 package matches your PCB footprint requirements. Ensure compatibility with external MOSFET selection for the 4-switch topology. Check RoHS compliance status through official manufacturer documentation before integration into production designs.
Selection Notes
Select this controller when designing systems requiring high input voltages up to 100V. Consider the 4-switch topology for bidirectional energy flow capabilities. Evaluate thermal performance based on the TSSOP-38 package limitations. Compare switching frequency options against electromagnetic interference constraints. Assess quiescent current requirements for standby mode applications.
Part Context
The LT8210 belongs to Analog Devices' family of high-voltage synchronous buck-boost controllers. This series addresses applications demanding wide input voltage ranges and efficient power conversion. The controller integrates advanced features like passthru mode and multiple operating modes. It serves as a core component in complex power management architectures requiring robust voltage regulation.
Replacement Considerations
LT8210EUJ#PBF is a pin-compatible alternative in QFN-40 packaging. Verify electrical parameter equivalence before substitution. Confirm mechanical footprint differences do not impact assembly processes. Review datasheet specifications for any functional variations between package types.
