illustrate

The LM2662/LM2663 CMOS charge pump voltage converter reverses a positive negative voltage in the voltage range of 1.5V to 5.5V. The LM2662/LM2663 uses two low-cost capacitors to provide a cost-free, 200 mA size output current, inductance, and EMI-related converter. With an operating current of only 300μA and an operating efficiency greater than 90% at maximum loads, the LM2662/LM2663 are ideal for battery-powered systems. The LM2662/LM2663 is also available as a positive voltage multiple.

The oscillator frequency can be reduced by adding an external capacitor to the oscillation pin. In addition, the OSC pin can be used to drive an external clock, the LM2662/LM2663. For the LM2662, a frequency control (FC) pin selects the frequency of the 20 kHz or 150 kHz oscillator. For the LM2663, the external off (standard deviation) pin function sector is replaced. The SD's pin can be used to disable the device, reducing the quiescent current by 10μA. The frequency of the LM2663 oscillator is 150 kHz.
