EUP3467AWIR1 from Eutech Microelectronics, in a SOP-8-EP. 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 | GND | power_in | Ground reference pin for the converter. |
| 2 | FB | input | Output feedback input, which receives the output voltage through the resistive divider; the datasheet gives the voltage error amplifier reference as 1.18 V (typical). |
| 3 | ISEN- | input | Current sense negative input; the constant current value is set by resistor R2 connected between ISEN- and ISEN+, and the absolute maximum rating for this pin is -0.3 V to 13 V. |
| 4 | ISEN+ | input | Current sense positive input; the constant current value is set by resistor R2 connected between ISEN+ and ISEN-, and the absolute maximum rating for this pin is -0.3 V to 13 V. |
| 5 | SW | power_out | Power switcher output; the switch voltage is rated -1 V to VIN + 0.3 V, and the exposed thermal pad must be connected to this pin. |
| 6 | VIN | power_in | Input supply pin; the recommended supply range is 8 V to 36V, with a 40 V input voltage surge rating and an absolute maximum of -0.3 V to 40 V. |
| 7 | OVEN | input | Over-voltage threshold setting pin; driving OVEN to a logic high turns off the converter, and the datasheet specifies an OVEN shutdown threshold voltage of 2.5 V. |
| 8 | COMP | passive | Loop compensation pin, where an RC network compensates the regulator loop from the transconductance error amplifier output. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
