7.3.9 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 23. Refer to application note, SNVA695 for information and design help when paralleling multiple LMZ31710 devices. Additionally, an EVM featuring two LMZ31710 devices operating in parallel can be evaluated using the LMZ31710X2EVM.
