Product Summary
The MAX1044CPA is a monolithic, CMOS switched-capacitor voltage converter that invert, double, divide, or multiply a positive input voltage. The MAX1044CPA is 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. The MAX1044CPA delivers 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. The applications of the MAX1044CPA include -5V Supply from +5V Logic Supply, Personal Communications Equipment, Portable Telephones, Op-Amp Power Supplies, EIA/TIA-232E and EIA/TIA-562 Power Supplies, Data-Acquisition Systems, Hand-Held Instruments and Panel Meters.
