Evaluates: MAX15303 MAX15303 Evaluation Kit General Description Features and Benefits The MAX15303 evaluation kit (EV kit) is a proven InTune Digital Point-of-Load (PoL) Switched-Mode application circuit design for the MAX15303 digital DC-DC Power Supply (SMPS) controller integrated circuit (IC). The EV kit allows the user Digital State-Space Control to easily modify and test the EV kit with different operating Dual-Edge-Modulated Pulse-Width Modulation conditions. The EV kit can be used as a standalone board (PWM) if desired. However, to take full advantage of the ICs 300kHz to 1MHz Switching Frequency capability, the user must connect the EV kit to a PC with 5V to 12V Input Voltage Range Using Linear Mode the Maxim PowerTool MAXPOWERTOOL002 USB-to- 6.5V to 12V Input Voltage Range Using BabyBuck PMBus interface dongle and then control and monitor Mode the EV kit with Maxims digital PowerTool graphical user 0.6V to 3.3V Output Voltage Range interface (GUI) software. The PowerTool GUI allows a PC 6A Output Current Capability Single-Phase Operation to control the PMBus interface and to collect real-time data from the EV kit. The PowerTool is Windows XP , Pin-Strap or PMBus Configuration Windows Vista , and Windows 7 compatible. It provides SMB Connectors for Low-Noise Measurements a simple interface for exercising the features of the IC. Connectors for Multiple-Rail Evaluation PMBus Interface for Control and Monitoring High-Speed Serial-Port Diagnostics Ordering Information appears at end of data sheet.
