LT8210EFE#PBF General Description

The LT8210 is a 4-switch synchronous buck-boost DC/DC controller that can operate in pass-thru, forced continuous, pulse-skipping and Burst Mode® operation. Pass-Thru is a feature that passes the input directly to the output when the input is within a user programmable window. Pass-Thru mode eliminates switching losses and EMI along with maximizing efficiency. For input voltages above or below the pass-thru window, the buck or boost regulation loops maintain the output at the set maximum or minimum values, respectively.

The GATEVCC driver supply is regulated to 10.6V allowing the use of standard-level MOSFETs and can be powered through the EXTVCC pin for improved efficiency. The GATEVCC regulator is back-drive-protected to ride through input brownouts while maintaining regulation. Optional reverse input protection down to –40V can be implemented with the addition of a single N-channel MOSFET. The LT8210 includes a precision current sense amplifier that can accurately monitor and limit output or input average current.
