ETA3512FSG from etasolution, in a SOT-563. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Feedback input. Connect an external resistor divider from VOUT to FB and GND to set the output voltage per VOUT = 0.6V x (1 + R1/R2). Internal reference VREF = 0.6V typical (0.594-0.606V at 25 C). |
| 2 | GND | power_in | Device ground return. Reference for input, output, and control signals. |
| 3 | IN | power_in | Supply voltage input, 2.5V to 5.5V (7.5V abs max). Bypass with a 10uF ceramic capacitor to GND placed as close as possible to the pin. |
| 4 | SW | power_out | Switching node, drain connection of the internal high-side and low-side power MOSFETs. Connect a 1uH inductor between SW and the regulator output. High-side Rds(on) = 100 mOhm typ, low-side Rds(on) = 60 mOhm typ; high-side current limit 4.5A typ. |
| 5 | EN | input | Enable input. Drive high (>=1.2V rising) to enable the converter, low (<=0.4V falling) to disable/shutdown. EN input current ~1uA at VEN=2V. Do not float. |
| 6 | PG | output | Power Good open-drain output. High impedance when the output voltage is within regulation (approximately 90% to 120% of the FB threshold, 5% hysteresis); pulled low otherwise. Requires an external pull-up resistor (e.g. 100k to VIN or logic rail). |
