EVAL-LT8210-1-AZ

EVAL-LT8210-1-AZ is an evaluation circuit for 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. The EVAL-LT8210-1-AZ can be operated in three modes: continuous conduction mode (CCM), discontinuous conduction mode (DCM), and pass-thru mode. The board operates at a switching frequency of 205kHz and is synchronized externally. All components on the board are selected to optimize efficiency at this frequency.

• Built-in multiphase current sharing (leader-less design)
• Pass-thru or fixed output CCM, DCM operation
• Programmable non-switching pass-thru Window
• Reverse input protection to -40V
• Programmable current limit
• No top MOSFET refresh noise in buck or boost
• Fixed/phase-lockable frequency: 80kHz to 400kHz
• Available in a 40-Lead (6mm x 6mm) QFN
