Parallel Operation
Up to six LMZ31710 devices can be paralleled for increased output current. Multiple connections must be made
between the paralleled devices and the component selection is slightly different than for a stand-alone
LMZ31710 device. A typical LMZ31710 parallel schematic is shown in Figure 27. Refer to application note,
SNVA695 for information and design help when paralleling multiple LMZ31710 devices.
