The VDD power terminal for the device requires the placement of electrolytic capacitor as energy storage capacitor because of the 1-A drive capability of the UCCx808A-x controller. Also a low-ESR noise decoupling capacitor is required and it must be placed as close as possible to the VDD and GND pins. Ceramic capacitors with stable dielectric characteristics over temperature are recommended. X7R is a suitable dielectric material for use here.
TI recommends a 10-µF, 25-V electrolytic capacitor part.
