SNVS135E – SEPTEMBER 1999 – REVISED DECEMBER 2014 LM2660 Switched Capacitor Voltage Converter
1 Features 3 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 ВµA and operating efficiency greater than 90% at
most loads, the LM2660 provides ideal performance
for battery-powered systems. LM2660 devices can be
operated directly in parallel to lower output
impedance, thus providing more current at a given
voltage. 1 Inverts or Doubles Input Supply Voltage
