The STEVAL-ISQ009V1 demonstration board is composed of three identical sections (daughterboards) and a motherboard. Each daughterboard is capable of performing DC-DC conversion starting from +5 VDC and is designed to deliver 3.3 V / 5 A to the load. The input terminals of the motherboard are connected to a +5 VDC external source and the output terminals to the load. The board can accommodate up to three DC-DC converters. The motherboard contains the circuitry necessary to perform current sharing (utilizing the L6615) and to isolate a failed section from the load. It is designed to be adaptable to all power supplies (compatible with the L6615 absolute maximum ratings) having remote sense pins. By changing just a few components, it can be modified for new specifications. It is possible to build a system to supply a 10 A load at +3.3 V in a 2+1 redundant configuration. That is, whenever three sections are running, each of them supplies 3.33 A, a value lower than its no
