14. Typical application circuit
The input DIN and output DOUT, need to be connected in series if necessary, the size of the protection resistance R depends on the number of cascade leds,
the more the number of cascades, the smaller the resistance value, the general recommendation is between 510-620 ohms, the recommended value is 560 ohms.
Typical application circuit parameters include power input voltage VCC, current limiting resistor RV, chip VDD voltage regulator CIN, input/output protection resistor RD.
Chip supply voltage VDD: VDD=VCC-(IDD+IIN)*RV,
The chip IIN is the operating current of the voltage regulator circuit inside the chip, IDD is the static current, and the RV resistance value ensures VDD>7V.
