KP41142SGA from Kiwi Instruments, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | IC reference ground; also serves as the source of the internal power MOSFET. Tied to pins 2 and 3 externally. |
| 2 | GND | power_in | IC reference ground; also serves as the source of the internal power MOSFET. Tied to pins 1 and 3 externally. |
| 3 | GND | power_in | IC reference ground; also serves as the source of the internal power MOSFET. Tied to pins 1 and 2 externally. |
| 4 | VDD | power_in | IC supply pin. Fed by the internal high-voltage supply block from the Drain (no auxiliary winding needed). VDD regulated at 6.4/7.1/7.8 V (min/typ/max) with Drain=12 V; UVLO on/off ~3.1/2.8 V; VDD clamp ~9 V at 5 mA. Absolute max 9 V DC, 5 mA DC clamp current. |
| 5 | Drain | power_in | Drain of the built-in 40 V power MOSFET. Connects to the secondary-side rectification node. Operating range -0.3 V to 40 V; Rds_on = 11.5 mΩ typ / 15 mΩ max (KP41142, VGS=4.5 V, ID=10 A). Tied to pins 6, 7, 8 externally. |
| 6 | Drain | power_in | Drain of the built-in 40 V power MOSFET. Tied to pins 5, 7, 8 externally. |
| 7 | Drain | power_in | Drain of the built-in 40 V power MOSFET. Tied to pins 5, 6, 8 externally. |
| 8 | Drain | power_in | Drain of the built-in 40 V power MOSFET. Tied to pins 5, 6, 7 externally. |
