Parallel Operation
Up to six LMZ31506 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
LMZ31506 device. A typical LMZ31506 parallel schematic is shown in Figure 26. Refer to application note,
SLVA574 for information and design help when paralleling multiple LMZ31506 devices.
