SCT2230ATVAR from SCT, in a SOT-563. 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 | VIN | power_in | Power supply input (4.2V-17V). Supplies power to the IC and the step-down converter switches. Bypass VIN to GND with a suitably large ceramic capacitor (≥0.1uF local, additional 10uF bulk if supply is more than a few inches away). |
| 2 | SW | power_out | Power switching output (switching node). Connect the output LC filter from SW to the output load. A capacitor (0.1uF or greater ceramic) is required from SW to BST to power the high-side switch. Absolute max -1V to 20V (-2.5V to 22V for <10ns pulses). |
| 3 | GND | power_in | Power ground. Must be soldered directly to the ground plane. |
| 4 | BST | power_in | Bootstrap power supply for the high-side power MOSFET gate driver. Must connect a 0.1uF or greater ceramic capacitor between BST and SW. |
| 5 | EN | input | Enable logic input. Floating the pin enables the device via an internal 1.5uA pull-up. Precision enable thresholds 1.18V rising / 1.1V falling with 5.5uA hysteresis current allow programmable UVLO threshold and hysteresis via an external divider from VIN. |
| 6 | FB | input | Buck converter output feedback sensing voltage. Connect a resistor divider from VOUT to FB to set the output voltage. Internal reference is 0.8V typical (0.792-0.808V at 25°C). |
