The EVK can be used as a standalone board if desired. However, to access the internal registers and to takefull advantage of the IC’s capability, the user must connect the EVK kit to a PC with Active Semi’s USB-TO-I2Cinterface dongle and use the GUI software. The EVK provides full access to the each converter’s input andoutput voltage, as well as all the digital control signals. This gives the user the flexibility to configure the EVKto match their real world system. Note that the ACT4910EVK1-121 is specifically configured for theACT4910QW121 IC.
