Changjing · DC-DC Converters · SOT-23-6L
CJ9340T6 from Changjing, in a SOT-23-6L. 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 | SW | output | Power switch output and drain of the internal MOSFET; connect the power inductor and output rectifier to SW, which can swing between GND and 28V. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | FB | input | Feedback input with a 0.6V feedback voltage; connect a resistor divider to FB to set the output voltage. |
| 4 | EN | input | Regulator on/off control input where a high input turns the converter on and a low input turns it off; connect to the input supply for automatic startup when not used. |
| 5 | IN | power_in | Input supply pin that must be locally bypassed. |
| 6 | NC | unconnected | Not connected. |
