The MAX8893 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the highly integrated MAX8893C power-management IC. The MAX8893 EV kit operates from a 2.7V to 5.5V input supply range and is controlled by an I²C interface. The MAX8893C integrates a high-efficiency step-down DC-DC converter, five low-dropout (LDO) linear regulators with programmable output voltages, individual power on/off control inputs, a load switch, and a USB high-speed switch. The I²C interface controls all the regulator output voltages, load switch timing, individual enable/disable control, and other parameters.
The MAX8893 EV kit also includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX8893C. To evaluate the MAX8893C, order the CMAXQUSB+ command module along with the MAX8893 EV kit.
The MAX8893C evaluation software can be downloaded from www.maximintegrated.com/evkitsoftware. The MAX8893 EV kit can also be used to evaluate the MAX8893A and MAX8893B. To evaluate the MAX8893A or MAX8893B, order a free sample along with this EV kit.
