# SY7072AABC

**Silergy Corp** · DC-DC Converters · SOT-23-6

SY7072AABC from Silergy Corp, 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 | LX | passive | Inductor node: connect the boost inductor between the IN pin and the LX pin. |
| 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 × (RFB1/RFB2 + 1). |
| 4 | EN | input | Enable pin: pull high to turn the device on, and do not leave it floating. |
| 5 | OUT | power_out | Output pin: decouple to GND with a minimum of 22µF ceramic capacitor. |
| 6 | IN | power_in | Input pin. |
