PRODUCTION DATA.
The VCC power-supply voltage should be well regulated. An electrolytic capacitor must be used to reduce the voltage ripple to less than 5% of the input voltage. Furthermore, the VLED voltage should be set to the voltage calculated by Equation 3:
where
Because the total current of the constant-current output is large, some electrolytic capacitors must be used to prevent the OUTXn terminal voltage from dropping lower than the calculated voltage from Equation 3.
