LT8210 4-Switch Buck-Boost DC/DC Controller

The LT®8210 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 efficien.
