MP5418GQG-Z from Monolithic Power Systems, in a QFN-10(1.4x1.8). 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 | GND | power_in | Power ground. |
| 2 | EN | input | On/off control: pulling EN higher than 0.8V enables the device, while floating EN or pulling it to ground disables it. |
| 3 | CTL | input | Analog input voltage; the VOUT2 voltage will be -1x the CTL pin voltage. |
| 4 | N/C | unconnected | Recommended to be connected to ground. |
| 5 | VOUT2 | power_out | Negative linear regulator output; a decoupling capacitor is needed. |
| 6 | GND | power_in | Power ground. |
| 7 | VOUT1 | power_out | Negative charge pump output; a decoupling capacitor is needed. |
| 8 | CN | passive | Negative terminal of the fly capacitor. |
| 9 | CP | passive | Positive terminal of the fly capacitor. |
| 10 | IN | power_in | Supply voltage: the device operates from a +2.3V to +5V unregulated input and a decoupling capacitor is needed to prevent large voltage spikes at the input. |
