isolated 12V buses deliver power to any number of non-isolated, step-

down buck regulators. LSN D12 DC/DC's accept a 12V input (10.8V

to 13.2V input range) and convert it, with the highest efﬁciency in the

smallest space, to a 1, 1.1, 1.2, 1.3, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output

... If the output current exceeds it maximum rating by typically 70% (17 Amps the output voltage drops to less than 98 original value, the LSN D12's internal overcurrent-detection circuitry immediately turns off the converter, which then goes into a "hiccup" mode. While hiccupping, the converter will continuously attempt to restart itself, go into overcurrent, and then shut down ...

... Lastly, when LSN D12 SIP's are installed in system boards, they are obvi- ously subject to numerous factors and tolerances not taken into account here.
