General Description

The LM2682 is a CMOS charge-pump voltage inverter capable of converting positive voltage in the range of +2.0V to +5.5V to the corresponding doubled negative voltage of -4.0V to -11.0V respectively. The LM2682 uses three low cost capacitors to provide 10 mA of output current without the cost, size, and EMI related to inductor based circuits. With an operating current of only 150 µA and an operating efficiency greater than 90% with most loads, the LM2682 provides ideal performance for battery powered systems. The LM2682 offers a switching frequency of 6 kHz.

Features

  • Inverts then doubles input supply voltage
  • Small MSOP-8 package (mini SO-8) and SO-8 package
  • 90Ohm typical output impedance
  • 94% typical power efficiency at 10 mA

Applications

  • LCD contrast biasing
  • GaAs power amplifier biasing
  • Interface power supplies
  • Handheld instrumentation
  • Laptop computers and PDAs
