DESCRIPTION\n\nThe SCI7661C/M CMOS DC/DC Converter features high operational performance with low power dissipation.It consists of two major parts:the booster circuitry and the regulator circuitry.The booster generates a doubledoutput voltage(-2.4V to-12V)or tripled output voltage(-3.6V to-18V)from the input(-1.2V to-6V).Theregulator is capable of setting the output to any desired voltage.The regulated voltage can be given one of threethreshold temperature gradients.  \n# ■ FEATURES\n\n●High performance with low power dissipation  \n●Simple conversion of VIN(-5V)to IVINI(+5V),2
