9 Power Supply Recommendations

The VDD power terminal for the device requires the placement of electrolytic capacitor as energy storage capacitor, because of UCCx808-x is controller with 1-A driver capability. And requires the placement of low-ESR noise-decoupling capacitance as directly as possible from the VDD terminal to the GND terminal, ceramic capacitors with stable dielectric characteristics over temperature are recommended, such as X7R or better. The recommended electrolytic capacitor is a 10-µF or 25-V capacitor.

The recommended decoupling capacitors are a 0.1-µF 0603-sized 25-V X7R capacitor.
