DETAILED DESCRIPTION
The TC1219/TC1220 charge pump converters invert
the voltage applied to the V
IN
pin. Conversion consists
of a two-phase operation (Figure 3-1). During the first
phase, switches S2 and S4 are opened and S1 and S3
are closed. During this time, C1 charges to the voltage
on V
IN
and load current is supplied from C2. During the
second phase, S2 and S4 are closed, and S1 and S3
are opened. This action connects C1 across C2,
restoring charge to C2.
