MAX1799 Evaluation System
General Description
The MAX1799 evaluation system (EV system) consists
of a MAX1799 evaluation kit (EV kit) and a companion
Maxim system management bus (SMBus鈩? interface
board.
The MAX1799 EV kit is an assembled and tested PC
board 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 (MAXSMBUS)
allows an IBM-compatible PC to use its parallel port to
emulate an Intel SMBus 2-wire interface. The 2-wire ser-
ial interface of the MAX1799 is I
2
C鈩?compatible.
Windows
廬
95/98/2000-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 MAX1799EVSYS for complete PC-based
evaluation of the MAX1799. Order the MAX1799EVKIT,
if you already have an SMBus interface.
