DC1203A: ORing 2 x 5A @ 48V (75V Max)

Summary

Demonstration Circuit 1203 showcases two LTC4357s in a 48V, 5A application. The circuits are operational over a range of 9V to 75V and are fully independent, with the exception of a common ground.

Input and output connections are made by 93 mil turrets which if removed, accommodate insertion of up to 12 gauge wire for in-situ testing. Adequate copper is available for use up to 20A, with appropriate MOSFETs.
