Introduction

AI Translation

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.

Features

AI Translation
  • 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
