Place ceramic decoupling capacitors as close as possible to the device pins. For the input supply, place the capacitor(s) between pin 3 (VINP) and pin 2 (GNDP). For the isolated output supply, place the capacitor(s) between pin 14 (VISO) and pin 15 (GNDS). This location is of particular importance to the input decoupling capacitor, because this capacitor supplies the transient current associated with the fast switching waveforms of the power drive circuits. The recommended capacitor value is 10 µF. Ensure the capacitor dielectric material is compatible with the target application temperature.
