VIPER222 Pin setting 1 Pin setting Figure 2. Connection diagram
GND 1 10 DRAIN VCC 2 9 DRAIN NC 3 8 DRAIN EA-IN 4 7 DRAIN EA-OUT 5 6 DRAIN
Table 1. Pin description SSOP10 Name Function
Connected to the source of the internal power MOSFET and controller ground 1 GND reference. Supply voltage of the control section. This pin provides the charging current of the 2 VCC external capacitor. 3 NC Not connected. The pin must be connected to GND pin. 4 EA-IN Input of the error amplifier. 5 EA-OUT Output of the error amplifier. High voltage drain pin. The start-up bias current is drawn from this pin too. Connect 6-10 DRAIN to a PCB copper area to facilitate the heat dissipation.
