ICE3A2065ELJFKLA1 from Infineon Technologies, in a DIP-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 | SoftS | passive | Soft-start and auto-restart control pin; an external capacitor to ground sets the soft-start and the adjustable blanking window before the IC enters Auto Restart Mode. |
| 2 | FB | input | Feedback input that provides regulation information to the internal protection unit and PWM comparator, and controls Active Burst Mode at light load. |
| 3 | CS | input | Current sense input connected to the series resistor in the source of the integrated depletion CoolMOS; when it reaches the internal current limit threshold the driver output is switched off immediately. |
| 4 | Drain | passive | Connection to the drain of the integrated depletion CoolMOS, rated 650V at Tj = 110°C; pin 4 is shorted to pin 5 within the DIP-8 package. |
| 5 | Drain | passive | Connection to the drain of the integrated depletion CoolMOS, rated 650V at Tj = 110°C; pin 5 is shorted to pin 4 within the DIP-8 package. |
| 6 | n.c. | unconnected | Not connected. |
| 7 | VCC | power_in | Positive controller supply pin with an operating range between 8.5V and 21V. |
| 8 | GND | power_in | Ground of the controller. |
