PN8149NSC-T1 from Wuxi Chipown Micro electronics, in a DIP-7. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Current sense pin, with the peak-current (OCP) threshold adjustable by an external resistor. |
| 2 | GND | power_in | Ground. |
| 3 | VDD | power_in | Operating supply voltage input pin, with an absolute maximum range of -0.3 to 32V. |
| 4 | COMP | input | Feedback pin, with an operating voltage range of -0.3 to 5.5V. |
| 5 | NC | unconnected | No connect (empty pin). |
| 7 | SW | passive | High-voltage power MOSFET pin connected to the transformer primary, rated 650V maximum. |
| 8 | SW | passive | High-voltage power MOSFET pin connected to the transformer primary, rated 650V maximum. |
