Active Power Filter only Evalvation Board
Although the IXHQ100 incorporates all the functions necessary to implement a state of the art negative voltage hot swap, a key feature of the IXHQ100 is its Power Active Filter. For those size and cost sensitive applications requiring only a Power Active Filter, the evaluation board schematic is given in Figure 1,with bill of materials in Figure 4. Figure 2 is aripple rejection plot of the Power Active Filter placed in the test circuit provided in Figure 3. Some of the advantages of a Power Active Filter over standard passive filters are: * Significantly reduced size of the power supply bypass capacitors. * Eliminate magnetic noise generation by eliminating the need for power filter inductors. * Reduced sensitivity to power supply noise. * Reduce size, weight, and overall system cost.
