ABSTRACT:
A voltage step-up circuit, or booster circuit, wherein in response to a first signal a first switching element is enabled to charge a first capacitor with an input voltage while a second switching element is disabled, and in response to a second signal the second switching element is enabled to charge with the input voltage a second capacitor connected in series to the first capacitor while the first switching element is disabled. The sum of the voltages appearing across the first and second capacitors is derived as an output voltage. The "ON" and "OFF" times of the first and second signals may be varied, and the ratio between the "ON" time of the first signal to the "ON" time of the second signal may also be varied. The number of switching elements and capacitors may be increased as needed.
