Overview
The TPS2413DRG4, produced by Texas Instruments, is a power rail controller designed for N+1 and ORing power supply applications. This device, in conjunction with an external N-channel MOSFET, emulates the function of a low forward voltage diode, providing a more efficient and tunable alternative to traditional diodes. The TPS2413 is particularly suited for systems requiring redundant power supplies or power buses, such as rack servers, blade servers, merchant network and server power supplies, battery backup units, and telecom systems.
