LM3414SDX from Texas Instruments, in a SON-8-EP(3x3). 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 | VCC | power_out | Internal regulator output that must be bypassed to ground with a ceramic capacitor of at least 1 µF. |
| 2 | PGND | power_in | Power ground and reference point for all stated voltages, which must be externally connected to EP and GND. |
| 3 | IADJ | input | Average output current adjustment pin; a resistor RIADJ from this pin to ground sets the average output current. |
| 4 | GND | power_in | Analog ground for internal circuitry, which must be connected to PGND external to the package. |
| 5 | FS | input | Switching frequency setting pin; a resistor RFS from this pin to ground sets the switching frequency. |
| 6 | DIM | input | PWM dimming control pin where a logic-level PWM signal sets the intended brightness of the LED string. |
| 7 | LX | output | Drain of the integrated N-MOSFET switch, connected to the output inductor and the anode of the Schottky diode. |
| 8 | VIN | power_in | Input voltage pin rated 4.5 V to 42 V for LM3414 (4.5 V to 65 V for LM3414HV). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
