Overview

  • Inverts Input Supply Voltage
  • 99% Voltage Conversion Efficiency
  • 25 mA Output Current
  • Shutdown Function
  • Requires Only Two Capacitors
  • 1 µF Capacitors
  • 18 Ω Output Resistance
  • +1.5 V to +5.5 V Input Range
  • 600 µA Quiescent Current

The ADM8828/ADM8829 is a charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative –1.5 V to –5.5 V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge pump. Output currents up to 25 mA with greater than 99% efficiency are achievable.

The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quiescent current to 20 nA.

The ADM8828/ADM8829 is available in a 6-lead SOT-23 package.
