# ICW6216

**ICW** · DC-DC Converters · SOP-7

ICW6216 from ICW, in a SOP-7. 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 | VDD | power_in | Chip supply pin that also serves as the output voltage feedback input when FB is floating; a 1uF ceramic capacitor is recommended, VDD_ON is 6.5V, VDD_OFF (UVLO) is 6.0V, VDD OVP threshold is 28V, and the internal clamp is 30V at 10mA. |
| 2 | GND | power_in | Chip reference ground. |
| 3 | FB | input | Feedback input pin with a 2.0V reference (1.97V to 2.03V); when left floating the output defaults to 14.3V, the OVP threshold is 2.4V and the OLP threshold is 1.87V. |
| 4 | CS | input | Peak current sense pin; when left floating the internal current limit defaults to 1.2A, the peak current threshold is 0.3V, and the abnormal overcurrent (AOCP) threshold is 0.6V. |
| 5 | Drain | passive | Drain of the internal high-voltage power MOSFET, rated for a 160V breakdown voltage with 0.81Ω typical on-resistance; datasheet lists pins 5 and 6 together in one row. |
| 6 | Drain | passive | Drain of the internal high-voltage power MOSFET, rated for a 160V breakdown voltage with 0.81Ω typical on-resistance; datasheet lists pins 5 and 6 together in one row. |
| 8 | GND | power_in | Chip reference ground. |

## CAD (KiCad official)

- Symbol: `ICW6216`
- Footprint: `Package_SO:SOIC-8-N7_3.9x4.9mm_P1.27mm`
- 3D model: SOP-7 (KiCad packages3D, STEP)
- 3D model files: `icw6216-etched.step` / `icw6216-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `icw6216.step` / `icw6216.glb` are the bare package body.
