## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD-G | power_in | Internal driver supply input, connected through a resistor to VDD. |
| 2 | VDD | power_in | Supply input; recommended operating range is 10-23 V, with an absolute maximum of 30 V, and the IC enters overvoltage protection above 24 V. |
| 3 | FB | input | Voltage feedback pin for an external optocoupler; recommended input range is 0-5 V, absolute maximum -0.3 to 6.0 V. |
| 4 | CS | input | Current sense pin (connected to the power MOSFET source) for an external sense resistor; recommended input range is -0.3 to 5.0 V, with peak current limit of 1.0-1.1 V. |
| 5 | DRAIN | passive | Power MOSFET drain; drain-source breakdown voltage is 650 V minimum (VGS=0 V, ID=250 uA). |
| 6 | DRAIN | passive | Power MOSFET drain (same net as pin 5); drain-source breakdown voltage is 650 V minimum (VGS=0 V, ID=250 uA). |
| 7 | GND | power_in | Ground pin, connected to system ground. |
| 8 | GND | power_in | Ground pin, connected to system ground (same net as pin 7). |
