LMR50410Y3FQDBVRQ1 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 | power_in | Bootstrap capacitor connection for high-side FET driver; connect 100-nF high-quality capacitor from this pin to SW pin. |
| 2 | GND | power_in | Power ground connected to low-side FET source internally; connect to system ground and input/output capacitor grounds with shortest possible path. |
| 3 | FB | input | Feedback input to converter for output voltage setting via resistor divider; never short this terminal to ground during operation. |
| 4 | EN | input | Precision enable input to converter with high = on and low = off; do not float, can be tied to VIN for self-startup or used with external UVLO divider. |
| 5 | VIN | power_in | Supply input terminal to internal bias LDO and high-side FET, operating range 4V to 36V; connect input supply and bypass capacitors directly to this pin. |
| 6 | SW | output | Switching output of the converter internally connected to source of high-side FET and drain of low-side FET; connect to power inductor. |
