MAX1681, MAX1680, Switched-Capacitor Voltage Converters
The MAX1680/MAX1681 inductorless switched-capacitor voltage converters either invert an input voltage of +2.0V to +5.5V or double it while supplying up to 125mA output current.
They have a selectable-frequency option that allows the use of small capacitors: 4.7µF (MAX1680), 1µF (MAX1681).
With their
MAX1681 Features
* o Selectable Switching Frequencies: 125kHz/250kHz (MAX1680) 500kHz/1MHz (MAX1681) o Allow Use of Small Capacitors (1µF for the MAX1681) o 125mA Output Current o 3.5Ω Output Impedance o 1µA Logic-Controlled Shutdown o Configurable as Voltage Inverters or Doublers o +2.0V to +5.5V Input Voltage Range
