AN-2241 SM72445 Evaluation Board
The SolarMagic™ SM72445 Evaluation Board is designed to demonstrate the operation and the
capabilities of the SM72445 MPPT controller. The board consists of a high efficiency, four-switch Buck-
Boost DC/DC converter and a bidirectional FET based switch designed to bypass the DC/DC converter for
cases when DC/DC conversion is not needed and during failure of the DC/DC converter (over-current
protection, over-temperature, and so forth). The board also includes auxiliary circuits such as driver,
current sensor, temperature sensor and additional OVP circuitry.
