1 Features 3 Description 1 The LM2662/LM2663 CMOS charge-pump voltage ? Inverts or Doubles Input Supply Voltage converter inverts a positive voltage in the range of 1.5 ? 3.5-Ω Typical Output Resistance V to 5.5 V to the corresponding negative voltage. The ? 86% Typical Conversion Efficiency at 200 mA LM2662/LM2663 uses two low cost capacitors to ? (LM2662) Selectable Oscillator Frequency: 20 provide 200 mA of output current without the cost, size, and EMI related to inductor based converters. kHz/150 kHz With an operating current of only 300 μA and ? (LM2663) Low Current Shutdown Mode operating efficiency greater than 90% at most loads, the LM2662/LM2663 provides ideal performance for 2 Applications battery powered systems. The LM2662/LM2663 may also be used as a positive voltage doubler. ? Laptop Computers ? Cellular Phones The oscillator frequency can be lowered by adding an ? Medical Instruments external capacitor to the OSC pin. Also, the OSC pin may be used to drive the LM2662/LM2663 with an ? Operational Amplifier Power Supplies external clock. For LM2662, a frequency control (FC) ? Interface Power Supplies pin selects the oscillator frequency of 20 kHz or 150 ? Handheld Instruments kHz. For LM2663, an external shutdown (SD) pin replaces the FC pin. The SD pin can be used to space disable the device and reduce the quiescent current space to 10 μA. The oscillator frequency for LM2663 is 150 kHz.
