The SP6661 Evaluation Board is designed with 2 complete SP6661 circuits on one board to help the user evaluate the performance of the SP6661 in both Inverter and Doubler modes. The evaluation board provides easy probe access points to all SP6661 Inputs and Outputs so that the user can quickly connect and measure electrical characteristics and waveforms of the Inverter or Doubler. The SP6661 Evaluation Board also provides a 3V to 5V 150mA DC to DC Converter using the SP6661 Doubler Circuit and a 5V LDO Regulator. The next two sections describe the SP6661 Board Layout and Using the SP6661 Evaluation Boards. A table of SP6661 Pin Assignments is also included with details on Input/Output pin function. A SP6661 Evaluation Board List of Materials table is provided with some manufacturers part numbers to use as a reference. Finally, a schematic is included of the SP6661 Evaluation Board.
