Protection to Current Loop Supply for Communications/Telecom

A solution for N+1 redundant systems that achieves both current sharing and OR-ing FET control. With current sharing, load current and power dissipation are distributed among multiple input power supplies. The combination of the current-sharing controller UCC39002 with the N+1 and OR-ing power rail Controller TPS2412 achieves true current sharing with reverse current protection
