ETA3486S2F

etasolution · DC-DC Converters · SOT23-5

ETA3486S2F from etasolution, in a SOT23-5. 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 the part and low to disable it, with EN input low at 0.4V max and input high at 1.5V min.
2 GND power_in Ground reference for the regulator; the datasheet recommends a large copper area on GND to cool the chip.
3 SW output Inductor connection: connect the inductor between SW and the regulator output; SW leakage is 10μA max at VIN=5.5V with VSW=0 or 5.5V and EN=GND.
4 IN power_in Supply voltage input for the regulator, operating from 2.6V to 5.5V, to be bypassed with a 10μF ceramic capacitor to GND.
5 FB input Feedback input: connect an external resistor divider from the output to FB and GND to set the output between 0.6V and VIN, with the FB threshold at 0.6V.
