## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Voltage feedback pin connected to the external optocoupler, with input impedance 6.0 kΩ, open-circuit voltage 4.2-5.2 V, overload threshold 3.7 V held for 50 ms before shutdown, and burst-mode entry at 1.4 V. |
| 2 | VDD | power_in | Supply input with start-up voltage 14.5-16.5 V, shutdown voltage 8.5-10.5 V, overvoltage protection at 23-24 V, clamp at 25-27 V (5 mA), and an absolute maximum of 30 V. |
| 3 | NC | unconnected | No-connect pin, left empty to maintain safe clearance between high and low voltage. |
| 4 | DRAIN | passive | Drain of the integrated power MOSFET, with a breakdown voltage of at least 650 V (BVDSS, VGS=0 V, ID=250 µA). |
| 5 | DRAIN | passive | Drain of the integrated power MOSFET, bonded together with pin 4 and rated at 650 V minimum breakdown voltage. |
| 6 | NC | unconnected | No-connect pin, left empty to maintain safe clearance between high and low voltage. |
| 7 | CS | input | Current-sense pin connected to the power MOSFET source through an external sense resistor, with input impedance 5.0 kΩ, peak current limit 1.0-1.1 V, valley limit 0.7-0.8 V, and absolute input range −0.3 to 5.0 V. |
| 8 | GND | power_in | Ground pin for the controller and system reference. |
