Abstract
A high voltage is generated from a low supply voltage by a charge pump driven with a pulse generator. A comparator compares the low supply voltage to a predetermined proportion of the high voltage. A low power voltage divider creates the predetermined portion of the high voltage. The comparator output drives the pulse generator, and the pulse generator output resets the comparator. A high voltage to low voltage mode may also be employed using the same arrangement.
