WebStandard QFN packages use bond-wires to connect the silicon die to the leadframe. Bond-wires add parasitic resistance and inductance between the die and the leadframe. Many DC/DC converters are now being designed using the HR QFN package technology, which eliminates bond-wires and minimizes the parasitic resistance and inductance.
