KP2143SGA from Kiwi Instruments, in a SOP-7. 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 | VDD | power_in | Chip supply pin. Recommended operating supply 11-27V. VDD_ON turn-on threshold ~16.3V, VDD_OFF turn-off ~9V, OVP threshold ~30V, internal clamp ~34.5V @ 7mA. |
| 2 | FB | input | System feedback pin. Auxiliary winding voltage is divided by resistors and fed to FB; used for CV-mode output-voltage regulation and CC-mode output-current regulation. Internal reference VFBREF = 2.0V; short-protection threshold VFB_SLP = 1.15V. |
| 3 | CC | input | Constant-current control pin. Requires a capacitor between CC and GND; typical recommended value 100nF. |
| 4 | CS | input | Current-sense input pin. Cycle-by-cycle over-current protection threshold Vcs(max) = 1.0V; leading-edge blanking time TLEB = 500ns. |
| 5 | Drain | passive | Drain of the internal 650V power MOSFET (tied together with pin 6). Rdson typical 2.6Ω (KP2143SGA). Absolute-max drain voltage -0.3V to 650V. |
| 6 | Drain | passive | Drain of the internal 650V power MOSFET (tied together with pin 5). Rdson typical 2.6Ω (KP2143SGA). Absolute-max drain voltage -0.3V to 650V. |
| 7 | GND | power_in | Chip reference ground. |
