The TCM828/TCM829 charge pump converters invert
the voltage applied to the V
of a two phase operation
phase, switches S2 and S4 are open, while S1 and S3
are closed. During this time, C1 charges to the voltage
on V
second phase, S2 and S4 are closed, and S1 and S3
are open. This action connects C1 across C2, restoring
charge to C2.
