♦ Miniature µMAX Package

The MAX1044 a nd ICL7660 a re monolithic , CMOS

switched-capacitor voltage converters that invert, dou-

ble, divide, or multiply a positive input voltage. They are

pin compatible with the industry-standard ICL7660 and

LTC1044. Operation is guaranteed from 1.5V to 10V with

no external diode over the full temperature range. They

deliver 10mA with a 0.5V output drop. The MAX1044

has a BOOST pin that raises the oscillator frequency

above the audio band and reduces external capacitor

size requirements.

♦ 1.5V to 10.0V Operating Supply Voltage Range

♦ 98% Typical Power-Conversion Efficiency

♦ Invert, Double, Divide, or Multiply Input Voltages

♦ BOOST Pin Increases Switching Frequencies

(MAX1044)

♦ No-Load Supply Current: 200µA Max at 5V

♦ No External Diode Required for Higher-Voltage

The MAX1044/ICL7660 combine low quiescent current

and high efficiency. Oscillator control circuitry and four

p owe r MOSFET s witc he s a re inc lud e d on-c hip .

Applications include generating a -5V supply from a

+5V logic supply to power analog circuitry. For applica-

tions requiring more power, the MAX660 delivers up to

100mA with a voltage drop of less than 0.65V.
