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 capaci-
tors dominate.
Charge-Pump Holding Capacitors
The holding capacitors (bypassing HPVSS to HPGND
and HPVDD to HPGND) value and ESR directly affect the
ripple at HPVSS and HPVDD. 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.
Unused Pins
Table 40 shows how to connect the IC’s pins when circuit
blocks are unused.
