7.3 Power Supply Recommendations

The VDD power terminal for the device requires the placement of electrolytic capacitor as energy storage capacitor, because UCCx808-x is a controller with a 1A driver capability. The UCCx808-x device 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 10µF or 25V capacitor.

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