Product Overview

The MAX1044CPA+ is a monolithic CMOS switched capacitor voltage converter in 8 pin DIP package. This device inverts, doubles, divides or multiplies a positive input voltage. It is pin compatible with the industry standard ICL7660 and LTC1044 devices. It operates from 1.5V to 10V with no external diode over the full temperature range. The MAX1044 delivers 10mA with 0.5V output drop. The device combines low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. It has a BOOST pin that raises oscillator frequency above audio band and reduces external capacitor size requirements. Typical applications include generating -5V supply from +5V logic supply to power analogue circuitry, personal communications equipment, op-amp power supplies, EIA/TIA-232E and EIA/TIA-562 power supplies, data acquisition systems and panel meters.
  • 98% typical power conversion efficiency
  • Operating temperature range from 0°C to 70°C
  • Supply current of 30μA at TA = +25°C (pins 1 and 7 no connection, LV open)
  • No external diode required for higher voltage operation
  • Maximum output resistance of 100 ohm at TA = +25°C (IL = 20mA, fOSC = 5KHz, LV open)
  • Oscillator frequency of 5KHz at V+ = 5V and 1KHz at V+ = 2V
  • Voltage conversion efficiency of 99.9%
  • Oscillator impedance of 100Kohm at V+ = 5V
