MAX861 - Switched-Capacitor Voltage Converters
The MAX860/MAX861 charge-pump voltage converters invert input voltages ranging from +1.5V to +5.5V, or double input voltages ranging from +2.5V to +5.5V.
Because of their high switching frequencies, these devices use only two small, low-cost capacitors.
Their 50mA output makes switching regulators
