A method and apparatus is arranged to produce high precision output voltage matching in a multiple output power converter. A two-output voltage converter includes a positive and a negative voltage output that are approximately equal in magnitude. The power converter includes inductors, transfer capacitance circuitry, and a controlled switching circuit. In one operating mode, the switching circuit is closed, the inductors are charged, and energy from the input signal is stored in the transfer capacitance circuitry. In a second operating mode, the switching circuit is opened, and the stored energy is transferred to the output loads. The transfer capacitance circuitry is arranged to provide improved matching in the output voltages. The two-output power converter topology may be extended to provide multiple outputs.
