RT8058GQW from Richtek Tech, in a WQFN-16-EP(3x3). 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 | PGND | power_in | Power ground; connect this pin close to the (-) terminal of CIN and COUT. |
| 2 | PGND | power_in | Power ground; connect this pin close to the (-) terminal of CIN and COUT. |
| 3 | PGND | power_in | Power ground; connect this pin close to the (-) terminal of CIN and COUT. |
| 4 | FB | input | Feedback input that receives the feedback voltage from a resistive divider connected across the output, referenced to the internal 0.6V reference. |
| 5 | GND | power_in | Signal ground; return the feedback resistive dividers to this pin, which connects to PGND at one point. |
| 6 | NC | unconnected | No internal connection. |
| 7 | EN | input | Enable pin; a logic high enables the converter and a logic low shuts it down (VEN_H min 1.4V, VEN_L max 0.4V). |
| 8 | NC | unconnected | No internal connection. |
| 9 | VDD | power_in | Signal input supply, decoupled to GND with a capacitor; normally equal to PVDD, and the VDD-to-PVDD difference must be kept below 0.5V. |
| 10 | PVDD | power_in | Power input supply of the converter power stage, decoupled to PGND with a capacitor; input range 2.6V to 5.5V. |
| 11 | PVDD | power_in | Power input supply of the converter power stage, decoupled to PGND with a capacitor; input range 2.6V to 5.5V. |
| 12 | PVDD | power_in | Power input supply of the converter power stage, decoupled to PGND with a capacitor; input range 2.6V to 5.5V. |
| 13 | LX | output | Output of the converter from the internal power MOSFET switches; connect to the inductor. |
| 14 | LX | output | Output of the converter from the internal power MOSFET switches; connect to the inductor. |
| 15 | LX | output | Output of the converter from the internal power MOSFET switches; connect to the inductor. |
| 16 | NC | unconnected | No internal connection. |
| 17 | PGND | power_in | Exposed pad; must be soldered to a large PCB and connected to PGND for maximum power dissipation. |
