MAX1044 - Switched Capacitor Voltage Converter
The MAX1044 and ICL7660 are monolithic, CMOS switched capacitor voltage converters that invert, dual, divide, or multiply a positive input voltage. They are the industry standard ICL7660 and pin compatible with the LTC1044. Guaranteed to operate from 1.5V to 10V over temperature without external diodes. They provide a 0.5V output drop of 10mA. The MAX1044 has a BOOST pin that raises the oscillator frequency above the audio frequency band and reduces external capacitor size requirements. The MAX1044/ICL7660 combine low quiescent current with high efficiency. oscillator control circuit and four switches including on-chip power MOSFETs. Applications include power analog circuits that generate +5 V logic supplies from a -5V supply. For applications requiring more power, the MAX660 provides up to 100mA with a voltage drop of less than 0.65V.
