General Description
The MAX1932 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board. The EV kit con-
tains a MAX1932 step-up switching regulator that
includes an 8-bit DAC with an SPI-compatible serial
interface. The output of the step-up switching regulator
is configured for a range of 40V to 90V and can provide
up to 2mA. The EV kit is powered from a DC supply
providing 4.5V to 5.5V. The EV kit can be reconfigured
for an input voltage down to 3V.
The SPI-compatible serial interface can be connected
to an IBM-compatible PC parallel port for evaluation.
Windows
95/98/2000-compatible software provides a
user-friendly interface to demonstrate the features of
the MAX1932 IC. The program is menu driven and
offers a graphics interface with control buttons.
The MAX1932 EV kit features current-limit protection for
the output. The MAX1932 QFN package and small
external components permit the circuit area to be less
than 0.6in
0.9in.
