DETAILED DESCRIPTION

The TC1219/TC1220 charge pump converters invert

the voltage applied to the VIN 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 VIN 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.
