1 / 15 page LM2682 www.ti.com SNVS044B – NOVEMBER 1999 – REVISED MAY 2013 LM2682 Switched Capacitor Voltage Doubling Inverter Check for Samples: LM2682 1 FEATURES DESCRIPTION The LM2682 is a CMOS charge-pump voltage 2 • Inverts Then Doubles Input Supply Voltage inverter capable of converting positive voltage in the • Small VSSOP Package and SOIC Package range of +2.0V to +5.5V to the corresponding • 90 Ω Typical Output Impedance doubled negative voltage of −4.0V to −11.0V respectively. The LM2682 uses three low cost • 94% Typical Power Efficiency at 10 mA capacitors to provide 10 mA of output current without the cost, size, and EMI related to inductor based APPLICATIONS circuits. With an operating current of only 150 μA and • LCD Contrast Biasing an operating efficiency greater than 90% with most loads, the LM2682 provides ideal performance for • GaAs Power Amplifier Biasing battery powered systems. The LM2682 offers a • Interface Power Supplies switching frequency of 6 kHz. • Handheld Instrumentation • Laptop Computers and PDAs Typical Operating Circuit and Pin Configuration 8-Pin VSSOP or 8-Pin SOIC These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
