Charge-Pump Flying Capacitor
The value of the flying capacitor (connected between
C1N and C1P) affects the output resistance of the
charge pump. A value that is too small degrades the
device’s ability to provide sufficient current drive, which
leads to a loss of output voltage. Increasing the value
of the flying capacitor reduces the charge-pump output
resistance to an extent. Above 1FF, the on-resistance
of the internal switches and the ESR of external charge-
pump capacitors dominate.
Charge-Pump Holding Capacitor
The holding capacitor (bypassing HPVSS) value and
ESR directly affect the ripple at HPVSS. Increasing
the capacitor’s value reduces output ripple. Likewise,
decreasing the ESR reduces both ripple and output
resistance. Lower capacitance values can be used in
systems with low maximum output power levels. See the
Output Power vs. Load Resistance graph in the Typical
Operating Characteristics section for more information
