Texas Instruments · DC-DC Converters · SOT-23-6
LMR50410XFDBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); 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 100-nF capacitor from this pin to the SW pin. |
| 2 | GND | power_in | Power ground terminal connected to low-side FET source internally; connect to system ground and ground side of input and output bypass capacitors with the shortest possible path to input capacitor. |
| 3 | FB | input | Feedback input to set output voltage via resistor divider; never short to ground during operation. |
| 4 | EN | input | Precision enable input (high = on, low = off, do not float) allowing adjustable UVLO via external resistor divider or tying to VIN. |
| 5 | VIN | power_in | Supply input to internal bias LDO and high-side FET; connect to input supply and bypass capacitors which must be directly connected to this pin and GND. |
| 6 | SW | output | Switching output internally connected to high-side FET source and low-side FET drain; connect to power inductor. |
