LMR50410YFQDBVRQ1 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 | output | Bootstrap capacitor pin for high-side gate driver; connect 100-nF capacitor between this pin and SW. |
| 2 | GND | power_in | Power ground return path for internal FETs; connect to system ground and output capacitor return paths. |
| 3 | FB | input | Feedback input with 1.0V nominal reference voltage; connect resistor divider to set output voltage. |
| 4 | EN | input | Precision enable input; high level (>1.36V typical) enables and low level (<0.95V typical) disables converter, do not leave floating. |
| 5 | VIN | power_in | Input power supply terminal accepting 4V to 36V; connect input supply and bypass capacitors directly to this pin and GND. |
| 6 | SW | output | Switching output node connected to high-side FET source and low-side FET drain; connect to inductor for step-down conversion. |
