LM2660 - Switched Capacitor Voltage Converter

General Description

The LM2660 CMOS charge-pump voltage converter is a versatile unregulated switched capacitor inverter or doubler.

Operating from a wide 1.5-V to 5.5-V supply voltage, the LM2660 uses two low-cost capacitors to provide 100 mA of output current without the cost, size and EMI related to inductorbased converters.

With an operating current of only 120 µA and operating efficiency greater than 90% at most loads, the LM2660 provides ideal performance for battery-powered systems.
