POWER CMOS DRIVERS WITH VOLTAGE TRIPLER
TC4626
TC4627
The voltage booster is an unregulated voltage tripler
circuit. The tripler consists of three sets of internal switches
and three external capacitors. S1a and S1b charge capaci-
tor C1 to VDD potential. S2a and S2b add C1 potential to VDD
input to charge C2 to 2 x VDD. S3a and S3b add C1 potential
to C2 to charge C3 to 3 x VDD. The position of the switches
is controlled by the internal 4 phase clock.
