9.1 Application Information

The TPS2412 and TPS2413 are designed to allow output ORing in N+1 power supply applications and input-power bus ORing in redundant source applications. The external MOSFET in conjunction with the TPS2412/13 emulate a discrete diode to perform this unidirectional power combining function.
