MAX660 Datasheet Switched Capacitor Voltage Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: MAX660 Switched Capacitor Voltage Converter November 1999 MAX660 Switched Capacitor Voltage.

General Description

The MAX660 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5V to 5.5V to the corresponding negative voltage.

The MAX660 uses two low cost capacitors to provide 100 mA of output current without the cost, size, and EMI related to inductor based converters.

With an operating current of only 120 µA and operating efficiency greater than 90% at most loads, the MAX660 provides ideal performance for battery powered systems.
