ETA2847S2G

etasolution · DC-DC Converters · SOT-23-6

ETA2847S2G from etasolution, in a SOT-23-6. 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 pin of the regulator, connected to the system ground.
2 SW output Inductor connection: connect an inductor between SW and the regulator output; SW voltage is limited to -0.3 V to VIN+0.3 V.
3 IN power_in Supply voltage input for the regulator, operating range 4.5 V to 28 V, absolute maximum 34 V; bypass with a 10 µF ceramic capacitor to GND.
4 FB input Feedback input: connect an external resistor divider from the output to FB and GND to set VOUT; the FB threshold is 0.596 V and FB voltage is limited to -0.3 V to 6 V.
5 EN input Enable pin: drive high to enable the part, low to disable it; EN rising threshold is 1.28 V and EN voltage is limited to -0.3 V to VIN+0.3 V.
6 BST passive Bootstrap pin: connect a 100 nF capacitor from this pin to SW; BST voltage is limited to -0.3 V to SW+6 V.
