Introduction

AI Translation

The MAX1719/MAX1720/MAX1721 capacitive charge pumps invert the voltage applied to their input. For highest performance, use low equivalent series resistance (ESR) capacitors (e.g., ceramic).

Features

AI Translation
  • Ultra-small monolithic, CMOS charge-pump inverters
  • Accept input voltages ranging from +1.5V to +5.5V
  • The MAX1720 operates at 12kHz, and the MAX1719/MAX1721 operate at 125kHz
  • High efficiency
  • Small external components
  • Logic-controlled shutdown
  • Oscillator control circuitry and four power MOSFET switches are included on-chip
  • Can deliver a continuous 25mA output current
  • 99.9% Voltage Conversion Efficiency
  • 50μA Quiescent Current (MAX1720)
  • Requires only two 1μF capacitors (MAX1719/MAX1721)

Applications

AI Translation
  • Local Negative Supply from a Positive Supply
  • Small LCD Panels
  • GaAs PA Bias Supply
  • Handy-Terminals, PDAs
  • Battery-Operated Equipment
