ETA1611S2G

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

ETA1611S2G 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 SW output Inductor connection: connect an inductor between SW and IN; the SW pin voltage is rated -0.3V to 25V absolute maximum.
2 GND power_in Ground pin for the device.
3 FB input Feedback input for current: connect an external resistor from FB to GND to set IOUT; FB is regulated to a 200mV typical reference and FB input current is 50nA max.
4 EN input Multi-functional control pin for enable and PWM dimming; the IC is disabled if this pin is floating, with EN input low below 0.6V and high at or above 1.2V.
5 IN power_in Input supply pin, operating from 2.7V to 6V; bypass with a 4.7μF or larger ceramic capacitor to GND.
6 NC unconnected Not connected internally; leave this pin floating.
