Abstract: A multiple output voltage generator includes a voltage divider and first and second voltage converters. The voltage divider receives a power voltage and divides the power voltage to generate a first output voltage. The first and second voltage converters are coupled to the voltage divider in parallel. The first voltage converter and the second voltage converter converting the first output voltage to respectively generate a second output voltage and a third output voltage.
