Product Details

The MAX1799 evaluation system (EV system) consists of a MAX1799 evaluation kit (EV kit) and a companion Maxim CMAXQUSB board.

The MAX1799 EV kit is an assembled and tested printed circuit board (PCB) that demonstrates the MAX1799 system power supply. The IC contains five programmable LDO linear regulators and two undedicated open-drain outputs. Each regulator can be individually adjusted from +1.8V to +3.3V. The two open-drain outputs can sink up to 150mA.

The Maxim SMBus interface board (CMAXQUSB) allows an IBM-compatible PC to use its USB port to emulate an Intel SMBus 2-wire interface. The 2-wire serial interface of the MAX1799 is I²C compatible. Windows® 98SE/2000/XP-compatible software provides a user-friendly interface to exercise the features of the MAX1799. The program is menu driven and offers a graphics interface with control buttons.

Order the MAX1799EVCMAXQU for complete PC-based evaluation of the MAX1799. Order the MAX1799EVKIT, if you already have an SMBus interface.
