A multiple output power supply is provided comprised of an input circuit for receiving an input signal, an auxiliary output circuit for carrying a self-regulated auxiliary output signal, and a main output circuit carrying a main power output signal. A feed forward compensation circuit receives and subtracts the auxiliary output signal from the input signal and in response generates a difference signal. A pulse width modulator receives and compares the main power output signal with the difference signal and in response gates the input signal, thereby regulating the main output signal and enabling current mode operation of the power supply. |
