KP2143SGA

Kiwi Instruments · AC-DC Controllers and Regulators · SOP-7

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.
