1. A power system, comprising:

  • a power supply controller for supplying a control signal;

    a plurality of MOSFET drivers controlled by said control signal; and

    a plurality of power supply channels wherein each power supply channel comprises a plurality of MOSFETs anda corresponding MOSFET driver of said plurality of MOSFET drivers andwherein said plurality of MOSFETs are controlled by said corresponding MOSFET driver, andwherein said plurality of power supply channels is configured to generate a plurality of power signals,wherein each of the plurality of MOSFET drivers have a same duty cycle characteristic andoperate synchronously with remaining MOSFET drivers andwherein said plurality of MOSFETs of each power supply channel comprises;

    a high side MOSFET coupled to a positive voltage source and to a load; and

    a low side MOSFET coupled to said load and a negative voltage source,wherein said high side MOSFET and low side MOSFET are configured as a switching mode power supply.
