DX3108E from Dersem, in a ESOP-8. 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 | NC | unconnected | No-connect pin, listed in the datasheet as a floating (悬空) port with no function. |
| 2 | NC | unconnected | No-connect pin, listed in the datasheet as a floating (悬空) port with no function. |
| 3 | CS1 | input | Output current setting port 1: the CS1 port voltage is rated -0.5 to 8 V, and the 576 to 624 mV (600 mV typical) reference sets the VIN-path current through RCS1. |
| 4 | CS2 | input | Output current setting port 2: the CS2 port voltage is rated -0.5 to 8 V, and the 576 to 624 mV (600 mV typical) reference sets the OUT-path current through RCS2. |
| 5 | OUT | bidirectional | Power input and constant-current output port 2: the OUT port voltage is rated -0.5 to 500 V, and the OUT output current is 5 to 60 mA. |
| 6 | CP | input | Constant-power setting port: it senses the OUT-side voltage through RCP for line-voltage compensation, with a port voltage rating of -0.5 to 8 V. |
| 7 | NC | unconnected | No-connect pin, listed in the datasheet as a floating (悬空) port with no function. |
| 8 | VIN | power_in | Power input and constant-current output port 1: the VIN port voltage is rated -0.5 to 500 V, and the VIN output current is 5 to 260 mA. |
| 9 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
