MP5418AGQG-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; enable above 1.2V, disable by floating or pulling to ground (internal 1MΩ resistor to GND), logic low below 0.4V.
3 CTL input Analog input voltage; the VOUT2 voltage is -1x the CTL pin voltage.
4 TM passive Test mode pin for factory use only; float TM or connect it to GND, and do not connect it to other pins.
5 VOUT2 power_out Negative linear regulator output (0V to VOUT1) that requires a decoupling capacitor, with 200mA typical load capability shared with VOUT1.
6 GND power_in Power ground.
7 VOUT1 power_out Negative charge pump output equal to -1x VIN that needs a decoupling capacitor, with absolute maximum rating of -6V to +0.3V.
8 CN passive Fly capacitor negative terminal.
9 CP passive Fly capacitor positive terminal, rated -0.3V to VIN + 0.3V.
10 IN1 power_in Supply voltage input operating from 2.3V to 5V unregulated, requiring a decoupling capacitor to prevent large voltage spikes.
