# QX2304L28T

**QX Micro Devices** · DC-DC Converters · SOT-23

QX2304L28T from QX Micro Devices, in a SOT-23. 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 | GND | power_in | Ground reference for the converter. Connect to the system ground plane. |
| 2 | LX | output | Internal power switch drain node. Connect the boost inductor between VIN and LX; peak switch current is rated up to 1000 mA (typ. 800 mA ILIMIT). |
| 3 | VOUT | power_out | Regulated output voltage feedback pin (2.8V for the L28 option). Also serves as the internal supply rail; connect to the output capacitor. Max rated voltage 7 V. |
