8.2.1.2 Detailed Hardware Design Procedure

Use the following procedure for the hardware design:

  • Determine the output power that is required into the load. The output power requirement determines the required power supply voltage and current. The output reconstruction filter components that are required are also driven by the output power.
  • With the requirements, adjust the typical application schematic in Figure 8-2.
