# SY7011AABC

**Silergy Corp** · DC-DC Converters · SOT23-6

SY7011AABC from Silergy Corp, in a SOT23-6. 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 | LX | passive | Inductor node: connect an inductor between the IN pin and the LX pin, with LX rated -0.3V to 6.0V (transients to -3V and +7V are tested for under 20ns). |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback pin: connect RFB1 between OUT and FB and RFB2 between FB and GND, with VOUT = 1.2V x (RFB1/RFB2 + 1) and a feedback reference of 1.182V to 1.218V. |
| 4 | EN | input | Enable pin: pull high to turn on and do not leave it floating, with a recommended range of 0V to VOUT+0.3V. |
| 5 | OUT | power_out | Output pin: decouple to GND with a minimum of 22µF ceramic capacitor, with a recommended operating range of 1.8V to 5.5V. |
| 6 | IN | power_in | Input pin with a recommended operating range of 0.85V to 5.5V. |
