# SK6630

**Suntek** · DC-DC Converters · SOT-23-6

SK6630 from Suntek, in a SOT-23-6. 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 | BS | power_out | Bootstrap pin: a capacitor connected between SW and BST is required to form a floating supply across the high-side switch driver. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | FB | input | Feedback input for the adjustable version; connect FB to the center point of the external resistor divider (VFB reference 0.585 V to 0.615 V, 0.6 V typical). |
| 4 | EN | input | Drive to a logic-high to enable the IC and to a logic-low to disable it and enter micro-power shutdown mode (rising threshold 1.4 V, falling threshold 0.8 V). |
| 5 | IN | power_in | Power supply pin; input voltage range is 4.5 V to 16 V, with an absolute maximum of 16 V. |
| 6 | SW | output | Switching pin, the switch node of the internal power MOSFETs; absolute maximum voltage is VIN+0.5 V and -0.3 V minimum. |

## CAD (KiCad official)

- Symbol: `SK6630`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `sk6630-etched.step` / `sk6630-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk6630.step` / `sk6630.glb` are the bare package body.
