SNOS405B – NOVEMBER 1999 – REVISED MAY 2017 MAX660 Switched Capacitor Voltage Converter
1 Features 3 Description The MAX660 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 MAX660 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 MAX660 provides ideal performance
for battery-powered systems. MAX660 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
