LMC7660 switch capacitor voltage converter
General description
LMC7660 is a CMOS voltage converter that can be used from+1.5V to+10V to the corresponding negative voltage to -1.5V to -10VLMC7660 for the industry for the industry Standard 7660. Features of inverter: running full temperature and voltage range, no external diode, low static current, high power efficiency. LMC7660 uses its built -in oscillator to switch 4 power MOS switches and charging two cheap electrolytic capacitors.

Electric characteristics (Note (Note 4)
Note 1: Absolute maximum rated value indicates the limit that the device may be damaged. During operation, DC and AC electrical specifications that exceed the rated working conditions. See Note 4.
Note 2: Connecting any input terminal to a voltage greater than V+or less than ground may cause destructive closednessLock. It is recommended not to input from the source before the LMC7660 power -on "
