**ChipLink Tech** · AC-DC Controllers & Regulators · SOP-8

CL2207SL from ChipLink Tech, in a SOP-8. 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 | VCC | power_in | Chip supply pin. Recommended operating range 11V to 27V. UVLO thresholds 16.3V/9.0V; absolute max 30V. Bypass to GND. |
| 2 | GND | power_in | Chip ground reference. |
| 3 | FB | input | Voltage feedback input. Connects to the resistor divider on the auxiliary winding to sense the reflected output voltage for constant-voltage regulation. Absolute max -0.3V to 7V. |
| 4 | CS | input | Current-sense input. Ties to the sense resistor Rcs on the MOSFET source path; used for peak-current control, OCP (500mV threshold) and constant-current regulation. Absolute max -0.3V to 7V. |
| 5 | DRAIN | power_out | Drain of the internal 650V high-voltage power MOSFET. Connects to the transformer primary winding. Pins 5/6/7/8 are internally tied together for thermal spreading. |
| 6 | DRAIN | power_out | Drain of the internal 650V high-voltage power MOSFET. Internally tied to pins 5/7/8. |
| 7 | DRAIN | power_out | Drain of the internal 650V high-voltage power MOSFET. Internally tied to pins 5/6/8. |
| 8 | DRAIN | power_out | Drain of the internal 650V high-voltage power MOSFET. Internally tied to pins 5/6/7. |

## CAD (KiCad official)

- Symbol: `CL2207SL`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `cl2207sl-etched.step` / `cl2207sl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cl2207sl.step` / `cl2207sl.glb` are the bare package body.
