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 doubled
output voltage(–2.4 to –12V) or tripled output voltage(–3.6 to –18V) from the input (–1.2 to –6V). The regulator is
capable of setting the output to any desired voltage. The regulated voltage can be given one of the three threshold
temperature gradients.
