DESCRIPTION
/ORDERING INFORMATION
The TL7660 is a CMOS switched-capacitor voltage converter that perform supply-voltage conversions from positive to negative. With only two noncritical external capacitors needed for the charge pump and charge reservoir functions, an input voltage within the range from 1.5 V to 10 V is converted to a plementary negative output voltage of
- 1.5 V to
- 10...
