Description

The ADM660ARZ is a CMOS switched-capacitor Voltage Converter that can be used to either invert the input supply voltage giving VOUT = -VIN or double it giving VOUT = 2VIN. 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 50mA with greater than 90% efficiency are achievable, while 100mA achieves greater than 80% efficiency. A frequency control (FC) input pin is used to select either 25 or 120kHz charge-pump operation. This is used to optimize capacitor size and quiescent current. With 25kHz selected, a 10µF external capacitor is suitable, while with 120kHz the capacitor may be reduced to 2.2µF.

  • Inverts or doubles input supply voltage
  • 2.2µF or 10µF Capacitors
  • 0.3V Drop at 30mA load
  • Low power CMOS (600µA quiescent current)
  • Selectable charge pump frequency (25 / 120kHz)
