The LM2780 is a charge pump that inverts an input voltage in the range of 1.8V to 5.5V to the corresponding output voltage of -1.8V to -5.5V.
With use of three or four low-cost external ceramic capacitors, the LM2780 can provide up to 50mA of output current.
The LM2780 operates at a 12kHz typical switching frequency to minimize supply current (60µA typ.).
