LMR50410YQDBVRQ1 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 connection for high-side FET driver; connect a high-quality 100-nF capacitor between CB and SW pins. |
| 2 | GND | power_in | Power ground terminal connected to source of low-side FET internally; connect to system ground, ground side of CIN and COUT with minimum trace length. |
| 3 | FB | input | Feedback input to converter for voltage regulation via resistor divider; set output voltage between 1V and 28V, never short to ground during operation. |
| 4 | EN | input | Precision enable input with control range 0.95V to 1.36V; do not float, can be tied to VIN, supports adjustable UVLO with external resistor divider. |
| 5 | VIN | power_in | Supply input terminal to internal bias LDO and high-side FET; accept 4V to 36V input with bypass capacitors directly connected to this pin and GND. |
| 6 | SW | output | Switching output of converter internally connected to high-side FET source and low-side FET drain; connect to power inductor. |
