AMS682 - INVERTING VOLTAGE DOUBLER

General Description

The AMS682 is a CMOS charge pump converter that provides an inverted doubled output from a single positive supply.

Requiring only three external capacitors for full circuit implementation the device has an on -board 12kHz (typical) oscillator which provides the clock.

Key Features

  • 99.9% Voltage Conversion Efficiency.
  • 92% Power Conversion Efficiency.
  • Wide Input Voltage Range +2.4V to 5.5V.
  • 185µA Supply Current.
  • Available in SO-8 and PDIP Packages.
  • Only 3 external Capacitors Required AMS682.
