TIDA-00270, Reference Design for the TPS74401, 6-A Current-Sharing Dual LDO

TIDA-00270, This power supply topology is capable of sourcing 6A via two LDOs operating in parallel. The solution sources current evenly between the two TPS74401's, each capable of supplying 3A. This design allows for higher currents to be supplied than is typically possible with a single LDO. It also allows for additional heat syncing not available with an individual LDO
