Switched-capacitor voltage converter in bipolar technology with 100mA output current

A voltage converter with 100mA output capability over a 3.5 - 15V range will be reported. Voltage loss is less than 1.2V at 100mA. A bipolar process has been used to obtain switch transistors with low on resistance and high emitter-base breakdown voltage. An adaptive non-overlapping switch drive optimizes efficiency.
