Description
- **Description**
- The LM2662/LM2663 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5 V to 5.5 V to the corresponding negative voltage. 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 μA 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.
- **Features**
- 1• Inverts or Doubles Input Supply Voltage
- • 3.5-Ω Typical Output Resistance
- • 86% Typical Conversion Efficiency at 200 mA
- • (LM2662) Selectable Oscillator Frequency: 20kHz/150 kHz
- • (LM2663) Low Current Shutdown Mode
- **Applications**
- • Laptop Computers
- • Cellular Phones
- • Medical Instruments
- • Operational Amplifier Power Supplies
- • Interface Power Supplies
- • Handheld Instruments
