MAX1681ESA+

The <bold>MAX1680/MAX1681</bold> 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 high output current capability, these charge-pump devices are suitable replacements for inductor-based regulators, which require more expensive external components and additional board space.

• Selectable Switching Frequencies: 500kHz/1MHz
• Allow Use of Small Capacitors: 1µF
• 125mA Output Current
• 3.5Ω Output Impedance
• 1µA Logic-Controlled Shutdown
• Configurable as Voltage Inverters or Doublers
• +2.0V to +5.5V Input Voltage Range
• 90% Efficiency

Applications
