# LP6498AB6F

**LOWPOWER** · DC-DC Converters · SOT-23-6

LP6498AB6F from LOWPOWER, 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 | NC | unconnected | No connection; this pin is not connected internally. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | FB | input | Feedback input; the output voltage is set by Vout = (R1/R2 + 1) × VFB, with VFB nominally 0.8V (0.784V to 0.816V). |
| 4 | EN | input | Enable pin; absolute maximum rating is -0.3V to 36V referenced to GND. |
| 5 | VIN | power_in | Voltage supply input, specified for 4.5V to 30V with absolute maximum of -0.3V to 36V to GND. |
| 6 | SW | output | Switch-mode connection to the inductor, connected to the drains of the internal main and synchronous power MOSFETs; absolute maximum rating is -0.3V to 36V. |
