Maxim ICL7660 CPA
ICL7660CPA Plus, made my Maxim. DC/DC Converter 1,5-10V DIP8. The ICL7660 is a monolithic, CMOS switched-capacitor voltage converter that inverts, doubles, divides, or multiplies a positive input voltage. It is pin compatible with the industry-standard ICL7660. Operation is guaranteed from 1,5V to 10V with no external diode over the full temperature range. It delivers 10mA with a 0,5V output drop. The ICL7660 combines low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. Applications include generating a -5V supply from a +5V logic supply to power analog circuitry.
