LMR33610BDDAR 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 | PGND | power_in | Power ground pin that connects to system ground and AGND with bypass capacitor using short wide traces. |
| 2 | VIN | power_in | Input supply to regulator rated 3.8 V to 36 V with high-quality bypass capacitor connected directly to this pin and PGND. |
| 3 | EN | input | Enable input to regulator where high = ON and low = OFF, can be connected directly to VIN, and must not float. |
| 4 | PG | output | Open-drain power-good flag output where high = power OK and low = power bad, pulls low when EN = low, and requires current limiting resistor to suitable voltage supply. |
| 5 | FB | input | Feedback input to regulator nominally 1 V for regulation, connected to tap point of feedback voltage divider, must not float or be grounded. |
| 6 | VCC | power_out | Internal 5-V LDO output (4.75 V to 5.25 V) supplying internal control circuits, requires 1-µF capacitor connected from this pin to GND, and must not be loaded with external circuits. |
| 7 | BOOT | power_in | Bootstrap supply voltage for internal high-side driver with 2.2 V undervoltage lockout threshold, requires 100-nF capacitor connected from this pin to SW. |
| 8 | SW | output | Regulator switch node driven between GND and VIN that connects to the power inductor. |
