Typical Connection Diagram
Fig 4 typical connection diagram

Power supply VS should have sufficient bypass capacitors to ensure proper operation, otherwise it may be unstable and reduce efficiency, and the output may be oscillated. Vcc power supply should be connected  a 0.1μF/50V ceramic capacitor with GND, Vs power supply should be connected a 0.1μF/100V ceramic capacitor and 100μf/100V Tantalum capacitor with GND, All bypass capacitors should be connected as close as possible to the corresponding power supply root.
Pin 11 is protection terminal ,users can connect with external protection circuit according to the control requirements. When the pin connect with high voltage(>2.7V),No output for protection When the pin is suspended, it works properly.
