LMR54410FDBVR from Texas Instruments, in a SOT-23-6. 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 | CB | passive | Bootstrap capacitor connection for the high-side FET driver; connect a 100nF quality capacitor between this pin and the SW pin. |
| 2 | GND | power_in | Power ground pin; internally connected to the source of the low-side FET; connect to system ground and the ground sides of CIN and COUT with minimum distance to CIN. |
| 3 | FB | input | Feedback input of the converter; connect resistor voltage divider to set output voltage; do not short-circuit to ground during operation. |
| 4 | EN | input | Precision enable input; cannot be left floating; high level = on, low level = off; can be connected to VIN; allows adjustable UVLO through external resistor divider. |
| 5 | VIN | power_in | Power supply input for internal bias LDO and high-side FET; connect to input power supply (4-36V) and input bypass capacitor CIN; bypass capacitor must be directly connected to this pin and GND. |
| 6 | SW | power_out | Switch output node; internally connected to the source of the high-side FET and drain of the low-side FET; connect to power inductor. |
