s DESCRIPTION
The SCI7661COA/MOACMOS 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.
