Complex devices such as <a href="page.php?w=system_on_a_chip">SOC</a> and <a href="page.php?w=Field-programmable_gate_array">FPGA</a> ICs usually require power from several voltage sources, with the latter sometimes having as many as ten or more rails. Electronic systems such as servers and industrial equipment also typically have multiple power rails.</p>
