SM3320-BATT-EV Charge Controller Reference Design (Rev. C)
The SM72442 MPPT digital controller and SM72295 photovoltaic full bridge drivers are designed to control
high-efficiency DC/DC conversion used in photovoltaic applications. This application report details the
usage of those devices in a battery charging application. The reference design is meant to provide support
for a wide variety of implementations, however, unless otherwise noted, this reference design system is
shown charging a 12V commercial automotive lead acid battery.
