Product Details

The MAX15303 evaluation kit (EV kit) is a proven application circuit design for the MAX15303 digital DC-DC controller integrated circuit (IC). The EV kit allows the user to easily modify and test the EV kit with different operating conditions. The EV kit can be used as a standalone board if desired. However, to take full advantage of the IC’s capability, the user must connect the EV kit to a PC with the Maxim PowerTool MAXPOWERTOOL002# USB-to-PMBus™ interface dongle and then control and monitor the EV kit with Maxim’s digital PowerTool graphical user interface (GUI) software. The PowerTool GUI allows a PC to control the PMBus interface and to collect real-time data from the EV kit. The PowerTool is Windows XP®, Windows Vista®, and Windows®7 compatible. It provides a simple interface for exercising the features of the IC.
