TPSY8120IABC from TECH PUBLIC, in a SOT-23-6. 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 | BS | passive | Boot-strap pin. Supplies the high-side gate driver. Decouple to LX with a 0.1 µF (100 nF) low-ESR ceramic capacitor. |
| 2 | GND | power_in | Ground return pin. Provide a low-impedance connection to the system ground plane; keep the CIN loop area between IN and GND small. |
| 3 | FB | input | Output feedback pin. Connect to the mid-point of the output resistor divider to program Vout = 0.6 V × (1 + R1/R2). Internal reference 0.6 V; FB input current ±50 nA. |
| 4 | EN | input | Enable control input. Pull high (VIH ≥ 2 V) to turn on the regulator; pull low (VIL ≤ 0.5 V) for shutdown. Do not float. Sink current ~1 µA. |
| 5 | IN | power_in | Power input pin, 4.5 V to 16 V (18 V abs. max). Decouple to GND with at least 1 µF (4.7 µF recommended) low-ESR ceramic capacitor placed close to the pin. |
| 6 | LX | power_out | Switching node. Connect to the output inductor. Internal high-side (90 mΩ) and synchronous low-side (70 mΩ) MOSFETs drive this node at 600 kHz. |
