EUP3482DIR1

Eutech Microelectronics · DC-DC Converters · SOP-8

EUP3482DIR1 from Eutech Microelectronics, in a SOP-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 BS power_in High-side gate drive boost input that supplies the high-side N-channel DMOS switch drive; connect a 0.01µF or greater capacitor from SW to BS.
2 IN power_in Input supply pin that powers the IC and the step-down converter switches; drive with a 4.5V to 30V source and bypass to GND with a suitably large capacitor.
3 SW power_out Power switching output that connects the output LC filter to the load and forms the boost return for the BS capacitor.
4 GND power_in Ground reference pin for the IC.
5 FB input Output feedback input that senses the output voltage through a resistive divider; the feedback threshold is 0.923V.
6 COMP passive Loop compensation input; connect a series RC network from COMP to GND to compensate the regulation loop.
7 EN input Enable logic input that turns the regulator on when driven high and off when driven low; it must not be left floating and can be connected directly to IN (or through a resistance) for automatic startup.
8 SS input Soft-start control input; connect an external capacitor to program the soft-start, or leave open to use the internal soft-start function.
