LP6483SPF from LOWPOWER, in a ESOP-8. 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 | NC | unconnected | No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience. |
| 2 | VIN | power_in | Supply input. Operating range 4.5V to 30V (36V absolute max, 32V typical OVP lockout). Bypass locally with 10uF x2 ceramic capacitors to GND. |
| 3 | SW | output | Switch node. Connects to the drains of the internal high-side and low-side power MOSFETs. Tie to the external inductor (typ. 10uH) to form the buck output stage. |
| 4 | GND | power_in | Ground return. Must be tied to the exposed pad (pin 9) and connected to the PCB ground plane for both current return and heat sinking. |
| 5 | FB | input | Feedback input to the internal error amplifier. Connect to the mid-point of the external R1/R2 output resistor divider; regulates to Vref = 0.6V (0.588-0.612V). VOUT = 0.6V x (1 + R1/R2). Absolute max -0.3V to 6V. |
| 6 | NC | unconnected | No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience. |
| 7 | EN | input | Enable control input. Drive above 2.5V (VEN(H)) to turn the converter on; drive below 0.4V (VEN(L) max 1V) to shut it down (I_SHDN < 0.1uA typ, 10uA max). Absolute max 36V; not internally pulled up. |
| 8 | NC | unconnected | No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience. |
| 9 | GND | power_in | Exposed thermal pad on the underside of the ESOP-8. Must be soldered to the PCB ground plane; ties to pin 4 GND and provides the primary heat path (theta_JA = 50 C/W). |
