SLM5418EJ-7G

Sillumin · DC-DC Converters · QFN-10(1.4x1.8)

SLM5418EJ-7G from Sillumin, 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 Enable input; set high (above about 0.9V) to enable the device, floating or pulled low disables it, with an internal 1MΩ resistor to ground.
3 CTL input Analog input voltage; the VOUT2 voltage will be -1x the CTL pin voltage.
4 NC unconnected No connect; leave this pin open.
5 VOUT2 power_out Negative linear regulator output (0V to VOUT1, up to 240mA typical current limit); a decoupling capacitor is needed.
6 GND power_in Power ground.
7 VOUT1 power_out Negative charge pump output (equal to -VIN unregulated); 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 Input power supply pin (2.3V to 5.5V); a decoupling capacitor is needed to prevent large voltage spikes at the input.
