RT8015BGQW from Richtek Tech, in a TDFN-10-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 | SHDN/RT | input | Oscillator resistor input: a resistor to ground sets the switching frequency (300kHz to 2MHz), and forcing this pin to VDD shuts the device down. |
| 2 | GND | power_in | Signal ground for all small-signal and compensation components, connected to PGND at one point. |
| 3 | LX | output | Internal power MOSFET switch output that connects to the inductor; the LX pin switch current is rated at 4A absolute maximum. |
| 4 | LX | output | Internal power MOSFET switch output that connects to the inductor; the LX pin switch current is rated at 4A absolute maximum. |
| 5 | PGND | power_in | Power ground that should be placed close to the negative terminal of CIN and COUT. |
| 6 | PVDD | power_in | Power input supply, decoupled to PGND with a capacitor, operating from 2.6V to 5.5V. |
| 7 | VDD | power_in | Signal input supply, decoupled to GND with a capacitor, normally equal to PVDD and operating from 2.6V to 5.5V. |
| 8 | PGOOD | output | Open-drain power good output that is pulled to ground when the output voltage is not within ±12.5% of the regulation point. |
| 9 | FB | input | Feedback input that receives the voltage from the output resistive divider, regulated against the 0.8V reference (0.784V to 0.816V). |
| 10 | COMP | passive | Error amplifier compensation point where external compensation elements are connected to stabilize the control loop. |
| 11 | Exposed Pad | passive | The datasheet lists this pad as No Internal Connection but states it must be soldered to a large PCB and connected to GND for maximum power dissipation. |
