Analog Devices LT8210 | Demoboard EVAL-LT8210-1-AZ

Description

The evaluation circuit EVAL-LT8210-1-AZ is a high voltage, high efficiency synchronous 4-switch multiphase buck-boost DC/DC converter with pass-thru mode. This circuit provides an output of 36V to 56V and can supply a maximum load current of 20A with an input voltage range of 26V to 80V. The evaluation circuit features four LT8210-1 controllers that operate in multiphase configuration, and the leaderless closed loop current sharing loop balances the current per phase.
