100 V, 99.9% Efficient Buck-Boost Supply with PassThru Window 

 The 100 V input LT8210 synchronous buck-boost controller features a unique, user-defined window for PassThru operation.

 This controller has a wide 2.8 V to 100 V input range-ideal for supplies in industrial, datacom, telecom, avionics, and automotive settings. This unique device can easily eliminate a number of traditionally required protection circuits, shrinking the BOM and improving efficiency system-wide.
