    ... Photovoltaic Full Bridge Driver General Description The SM72295 is designed to drive 4 discrete N type MOSFET’ full bridge configuration. The drivers provide 3A of peak current for fast efficient switching and integrated high speed bootstrap diodes. Current sensing is provided by 2 transconductance amplifiers with externally programmable gain and filtering to remove ripple current to provide average current information to the control circuit ...
