Positive Charge Pump Design Considerations
A single stage charge pump is shown above. The maximum
V ON output voltage is determined by the following equation:

S CPP S OUT1
where:
? R ONN and R ONP resistance values depend on the V DDP
voltage levels. For 12V supply, R ON is typically 33 Ω . For
6V supply, R ON is typically 45 Ω .
If additional stage is required, the LX switching signal is
recommended to drive the additional charge pump diodes.
The drive impedance at the LX switching is typically 150m Ω .
The figure below illustrates an implementation for two-stage
positive charge pump circuit.
