Abstract
A universal switching power supply for generating one or more output voltage levels wherein the power supply is operable over a range of AC and DC input supply voltages. The universal switching power supply achieves a ratio between the highest voltage and lowest voltage of at least 27. The universal switching power supply also features an intrinsically safe output. The intrinsically safe output circuitry comprises a multi-layer PCB with a planar core transformer.
