Charge-Pump Capacitor Selection (MAX9706)
Use capacitors with an ESR less than 100m
for opti-
mum performance. Low-ESR ceramic capacitors mini-
mize the output resistance of the charge pump. Most
surface-mount ceramic capacitors satisfy the ESR
requirement. For best performance over the extended
temperature range, select capacitors with an X7R
dielectric. Table 5 lists suggested manufacturers.
Flying Capacitor (C1, MAX9706)
The value of the flying capacitor (C1) affects the output
resistance of the charge pump. A C1 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 C1 reduces the charge-pump out-
put resistance to an extent. Above 1F, the on-resistance
of the switches and the ESR of C1 and C2 dominate.
Output Capacitor (C2, MAX9706)
The output capacitor value and ESR directly affect the
ripple at CPVSS. Increasing the value of C2 reduces
output ripple. Likewise, decreasing the ESR of C2
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. Charge-Pump Capacitance and Load Resistance
graph in the Typical Operating Characteristics. C2
must be equal to or greater than C1.
CPVDD Bypass Capacitor (MAX9706)
The CPVDD bypass capacitor lowers the output imped-
ance of the power supply and reduces the impact of
the MAX9706’s charge-pump switching transients.
Bypass CPVDD with a capacitor to CPGND and place it
physically close to CPVDD and CPGND. Use a value
that is equal to C1.
