Overview
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 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.
Applications
- Local Negative Supplies
- Interface Power Supplies
- Op-Amp Power Supplies
- MOSFET Bias
Key features
- The devices’ equivalent output resistance (typically 3.5Ω) allows them to deliver as much as 125mA with only a 440mV drop.
- A shutdown feature reduces quiescent current to less than 1µA.
- Selectable Switching Frequencies: 125kHz/250kHz (MAX1680) 500kHz/1MHz (MAX1681)
- Allow Use of Small Capacitors (1µF for the MAX1681)
- 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
- Available in 8-Pin SO Packages
- 90% Efficiency
