LM5163HQDDARQ1 from Texas Instruments, in a SO-8. 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 | GND | power_in | Ground connection for internal circuits. |
| 2 | VIN | power_in | Regulator supply input pin to high-side power MOSFET and internal bias regulator; connect directly to input supply with short, low impedance paths. |
| 3 | EN/UVLO | input | Precision enable and undervoltage lockout programming pin with converter shutdown below 1.1V, standby mode between 1.1V and 1.5V, and startup sequence initiation above 1.5V. |
| 4 | RON | input | On-time programming pin where external resistor to GND sets the buck switch on-time. |
| 5 | FB | input | Feedback input of voltage regulation comparator. |
| 6 | PGOOD | output | Open-drain power good indicator output pin requiring external pullup resistor between 10kΩ and 100kΩ to source voltage. |
| 7 | BST | power_in | Bootstrap gate-drive supply pin requiring 2.2nF 50V X7R ceramic capacitor between BST and SW to bias internal high-side gate driver. |
| 8 | SW | power_out | Switching node internally connected to high-side NMOS buck switch source and low-side NMOS synchronous rectifier drain, connecting to power inductor switching node. |
