Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input; recommended VDD range is 8 to 25V, with UVLO turn-on at 7.0V typical, UVLO turn-off at 18.2V typical, VDD over-voltage protection at 27.0V typical, and absolute maximum VDD of 28V. |
| 2 | GND | power_in | Ground reference pin for the controller. |
| 3 | FB | input | Voltage feedback input connected through a resistor divider to the auxiliary winding to sense the output voltage; reference voltage Vref is 2.475 to 2.525V and the absolute maximum input is -0.3 to 7V. |
| 4 | CS | input | Power MOSFET source and current-sense input via external sense resistor Rs, with a minimum over-current threshold of 485 to 515mV and a maximum of 590mV, and an absolute maximum input of -0.3 to 7V. |
| 5 | Drain | output | Drain of the internal 650V power MOSFET (BVdss 650V; off-state drain voltage limited to -0.3V to BVdss). |
| 6 | Drain | output | Drain of the internal 650V power MOSFET (BVdss 650V; off-state drain voltage limited to -0.3V to BVdss). |
| 7 | Drain | output | Drain of the internal 650V power MOSFET (BVdss 650V; off-state drain voltage limited to -0.3V to BVdss). |
| 8 | Drain | output | Drain of the internal 650V power MOSFET (BVdss 650V; off-state drain voltage limited to -0.3V to BVdss). |
