11 Power Supply Recommendations

Decouple the VCC power supply voltage by placing a 0.1-µF ceramic capacitor close to VCC pin and GND plane. Depending on panel size, several electrolytic capacitors must be placed on the board equally distributed to get a well regulated LED supply voltage (VLED). VLED voltage ripple must be less than 5% of its nominal value. Furthermore, set the VLED voltage as calculated by equation:

Equation 3. VLED > Vf + 0.4 V (10 mA constant current example)

where

  • Vf = maximum forward voltage of LED
