1 / 19 page LM2662, LM2663 www.ti.com SNVS002D – JANUARY 1999 – REVISED MAY 2013 LM2662/LM2663 Switched Capacitor Voltage Converter Check for Samples: LM2662, LM2663 1 FEATURES DESCRIPTION The LM2662/LM2663 CMOS charge-pump voltage 2 • Inverts or Doubles Input Supply Voltage converter inverts a positive voltage in the range of • 8-Pin SOIC Package 1.5V to 5.5V to the corresponding negative voltage. • 3.5 Ω Typical Output Resistance The LM2662/LM2663 uses two low cost capacitors to provide 200 mA of output current without the cost, • 86% Typical Conversion Efficiency at 200 mA size, and EMI related to inductor based converters. • (LM2662) Selectable Oscillator Frequency: 20 With an operating current of only 300 μA and kHz/150 kHz operating efficiency greater than 90% at most loads, • (LM2663) Low Current Shutdown Mode the LM2662/LM2663 provides ideal performance for battery powered systems. The LM2662/LM2663 may also be used as a positive voltage doubler. APPLICATIONS • Laptop computers The oscillator frequency can be lowered by adding an external capacitor to the OSC pin. Also, the OSC pin • Cellular phones may be used to drive the LM2662/LM2663 with an • Medical instruments external clock. For LM2662, a frequency control (FC) • Operational amplifier power supplies pin selects the oscillator frequency of 20 kHz or 150 kHz. For LM2663, an external shutdown (SD) pin • Interface power supplies replaces the FC pin. The SD pin can be used to • Handheld instruments disable the device and reduce the quiescent current to 10 μA. The oscillator frequency for LM2663 is 150 kHz.
