I'm designing a circuit that includes a boost converter with a few mysterious "optional" components and I'm trying to decide whether or not to include them. Does anyone know what they do? At first I thought they might be some filter but now I'm not sure. [Here's the datasheet][1] for the FitiPower FP6717 step-up converter chip.
