Voltage to the Demo Board is supplied through a 5.0 V DC power jack. The dc power is then translated down to the voltage levels required with Micrel voltage regulators. These voltage regulators were chosen for stability in evaluation and testing. A mass production design can use low cost voltage regulators to supply the KS8695PX.
