10 Power Supply Recommendations

The VCC power supply voltage should be decoupled by placing a 0.1-uF ceramic capacitor close to VCC pin and GND plane. Depending on panel size, several electrolytic capacitors must be placed on board equally distributed to get a well regulated LED supply voltage (VLED). VLED voltage ripple should be less than 5% of its nominal value.
