The MAX828 / 829 primary function is a voltage inverter. The device will convert 5.0 V into 5.0 V with light loads. Two
capacitors are required for the inverter to function. A third capacitor, the input bypass capacitor, may be required depending
on the power source for the inverter. The performance for this device is illustrated below.

Two or more devices can be cascaded for increased output voltage. Under light load conditions, the output voltage is
approximately equal to V
in
times the number of stages. The converter output resistance increases dramatically with each
additional stage. This is due to a reduction of input voltage to each successive stage as the converter output is loaded. Note that
the ground connection for each successive stage must connect to the negative output of the previous stage. The performance
characteristics for a converter consisting of two cascaded devices are shown below.
