ABSTRACT:
A switch mode power supply (10) including a switch control circuit (26), a switching device (28), and a plurality of transformers (38) and (40) is disclosed. Turns ratios of the transformers (38) and (40) are selected to produce desired output voltages within acceptable tolerances. A voltage from an output (46) is selected as a feedback voltage and is provided through an isolator (76) to the switch control circuit (26) for regulation thereof. The power supply (10) is characterized in that desired output voltages are produced without the use of supplementary voltage regulators. Output voltages from the transformers (38) are combined and rectified, as required, to produce needed derivative voltages.
