KP1466SPA from Kiwi Instruments, in a SOIC-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 | HVDD | power_in | High-voltage supply pin for the chip, rated -0.3 to 650 V absolute maximum, with HVDD turn-on at 13 to 17 V (typ 15.5 V) and undervoltage lockout at 4.8 to 6.8 V (typ 5.8 V). |
| 2 | NC | unconnected | Not connected; the datasheet states to leave this pin floating in use. |
| 3 | GATE | output | Gate drive output pin, with an absolute maximum voltage rating of -0.3 to 15 V. |
| 4 | CS | input | Current sense input pin, with an absolute maximum rating of -0.3 to 7 V, a constant-current output reference of 180 to 190 mV (typ 185 mV) and a peak current reference VCS_MAX of 1.4 to 1.6 V (typ 1.5 V). |
| 5 | ROVP | input | Output overvoltage protection setting pin, where an external resistor to GND sets the continuously adjustable OVP point proportional to its value, must not be shorted or left open, and OVP is recommended at 1.4 to 1.6 times the steady-state output voltage, with an absolute maximum rating of -0.3 to 7 V and a sourced output current of 40 µA. |
| 6 | NC | unconnected | Not connected; the datasheet states to leave this pin floating in use. |
| 7 | DIM | input | Output current adjust pin that accepts a PWM pulse signal (PWM frequency 0.6 to 10 kHz), with high and low decision thresholds of 1.9 to 2.1 V and 0.4 to 0.6 V, an absolute maximum rating of -0.3 to 7 V, and a PWM pulse width below 1 µs causing the chip to enter standby mode. |
| 8 | GND | power_in | Chip reference ground pin. |
