LMR36520FADDAR from Texas Instruments, in a SO-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 | PGND | power_in | Power and analog ground terminal serving as ground reference for internal circuits; all electrical parameters measured relative to this pin. |
| 2 | VIN | power_in | Input power supply to regulator with recommended range 4.2V to 65V; connect quality bypass capacitors directly to this pin and PGND. |
| 3 | EN | input | Enable input; high level enables operation, low level disables operation; can connect directly to VIN but must not be left floating. |
| 4 | PG | output | Open-drain power good flag output; provides high level when power is good and low level when power is bad or EN is low; must connect through current-limiting resistor to voltage supply. |
| 5 | FB | input | Feedback input connected to tap point of feedback voltage divider for regulator output voltage setting; must not be left floating. |
| 6 | VCC | power_out | Internal 5V LDO regulated output used as power supply for internal control circuit; do not connect to external loads; requires 1µF capacitor between this pin and PGND. |
| 7 | BOOT | power_in | Bootstrap power voltage supply for internal high-side gate driver; requires 100nF quality capacitor connected between this pin and SW pin. |
| 8 | SW | output | Regulator switch node driven by internal switching MOSFETs; connect to external power inductor for energy transfer during buck conversion. |
