... Fault and Error Propagation Z-series POL converters protect outputs by triggering either a fault or an error depending on the severity of the problem (see POL converter datasheets). Fault propagation between POL converters belonging to the same group is a programmable function of POL converters. The DPM allows propagating faults and errors between groups of POL converters and, in case of an error DC/DC front-end and an optional crowbar. The propagation delay for fault/error propagations is less than 10μ ...
