Selection of external capacitors
Low ESR capacitors are recommended for the input bypass capacitor, output smoothing capacitor, and charge pump
flying capacitor. Also, ceramic capacitors are recommended for their low fluctuations due to temperature (such as X5R
or X7R).
Adding LEDs for driving
Shown in Figures 5 and 6 are sample circuit diagrams illustrating the use of output voltage (VCP) of this IC when an
LED is added. Note that the IC may not be able to conform to its specifications if the total LED current exceeds 105mA.
To limit the amount of current to the additional LED, or to control the on/off switching of the current, it is necessary to
connect a resistor or switch in series with the added LED.
