Switched Capacitor Voltage Converter
The LM2662 LM2663 CMOS charge-pump voltage converter inverts a positive voltage in the LM2662 LM2663 uses two low cost capacitors to provide 200 mA of output current without the cost, size, and EMI related to inductor based converters. With an operating current of only 300 ?A and operating efficiency greater than 90% at most loads, the LM2662 LM2663 provides ideal performance for battery powered systems. The LM2662 LM2663 may also be used as a positive voltage doubler.
The Oscillator frequency CAN be lowered by adding an external capacitor to the OSC pin. Also, the OSC pin may be used to drive the LM2662 LM2663 with an external Clock For LM2662 a frequency control (FC) pin selects the Oscillator frequency of 20 kHz or 150 kHz. For LM2663 an external shutdown (SD) pin replaces the FC pin. The SD pin CAN be used to disable the device and reduce the quiescent current to 10 ?A. The Oscillator frequency for LM2663 is 150 kHz.
