## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | FB pin combines the functions of feedback control, selectable burst entry/exit control and overload/open loop protection. |
| 2 | VIN | power_in | VIN pin is connected to the bus via a resistor divider to sense the line voltage and combines the functions of input Line OVP, Brownout and minimum ZC count setting for low and high line. |
| 3 | CS | input | The CS pin is connected to the external shunt resistor for primary current sensing and to the internal PWM signal generator for switch-off determination together with the feedback voltage. |
| 4 | ZCD | bidirectional | ZCD pin combines the functions of start-up, zero crossing detection and output over voltage protection, and during start-up it provides a voltage level to the gate of the power switch CoolMOS to charge the VCC capacitor. |
| 5 | DRAIN | passive | The DRAIN pin is connected to the drain of the integrated CoolMOS. |
| 7 | VCC | power_in | The VCC pin is the positive voltage supply to the IC, and its operating range is between VVCC_OFF and VVCC_OVP. |
| 8 | GND | power_in | The GND pin is the common ground of the CoolSET. |
