ETA3418S2F
etasolution · DC-DC Converters · SOT-23-5
ETA3418S2F from etasolution, in a SOT-23-5. 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 | EN | input | Enable pin for the IC: drive high to enable and low to disable, with EN rising threshold 1.2V and falling threshold 0.4V, and the pin defaults low when floating. |
| 2 | GND | power_in | Ground reference pin for the regulator; connect it to a large copper area to cool the chip and improve thermal performance. |
| 3 | SW | output | Inductor connection: connect an inductor between SW and the regulator output, with the high-side current limit specified at 3A. |
| 4 | IN | power_in | Supply voltage input with a 2.6V to 7V input range, to be bypassed with a 10µF ceramic capacitor to GND, and with UVLO rising at 2.35V typical. |
| 5 | FB | input | Feedback input: an external resistor divider from the output to FB and GND sets the output between 0.6V and VIN, with the FB threshold at 0.6V (0.588V to 0.612V). |
