LM5163DDAR from Texas Instruments, in a ESOP-8. 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 | 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; input voltage range 6 V to 100 V. |
| 3 | EN/UVLO | input | Precision enable and undervoltage lockout pin; converter in shutdown mode below 1.1 V, standby mode from 1.1 V to 1.5 V, and normal operation above 1.5 V. |
| 4 | RON | input | On-time programming pin; external resistor to GND sets buck switch on-time inversely proportional to input voltage. |
| 5 | FB | input | Feedback input to voltage regulation comparator maintained at internal reference voltage of 1.2 V. |
| 6 | PGOOD | output | Open-drain power good indicator output requiring external pullup resistor of 10 kΩ to 100 kΩ to indicate output voltage regulation status. |
| 7 | BST | power_in | Bootstrap gate-drive supply pin for high-side gate driver requiring 2.2 nF 50 V X7R ceramic capacitor connected between BST and SW. |
| 8 | SW | power_out | Switching node internally connected to source of high-side NMOS buck switch and drain of low-side NMOS synchronous rectifier; externally connected to power inductor. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
