KP201CSGA

KIWI · AC-DC Controllers & Regulators · SOP-8

KP201CSGA from KIWI, in a SOP-8. 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 CT output Overload protection time setting pin; an external capacitor to ground sets the overload protection time.
2 VDD power_in Chip supply pin; recommended 10 to 28 V operating range, 33 V absolute maximum, with UVLO on at 21 V typ and off at 9 V typ.
3 FB input Feedback input connected to the optocoupler in closed loop; its voltage sets the PWM drive frequency and the CS turn-off threshold (-0.3 to 7 V).
4 CS input Current sense input and CS OVP detection pin (-0.3 to 7 V), with CS OVP threshold of 250 mV.
5 NTC passive External OTP detection pin, with 110 uA detection current and 1.0 V trigger threshold.
6 NC unconnected No connection.
7 GND power_in Chip ground.
8 GATE output Totem-pole gate drive output connected to the external MOSFET, with 13 V output high clamp and 20 V absolute maximum.
