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.
