APPLICATIONS INFORMATION
output capacitor is too large, the crossover frequency can
decrease too far below the compensation zero and also
lead to degraded phase margin. Table 3 provides a guide-
line for the range of allowable values of low ESR output
capacitors assuming a feedforward capacitor is used.
See the Output Voltage Programming section for more
details on selecting a feedforward capacitor. Larger value
output capacitors can be accommodated provided they
have sufficient ESR to stabilize the loop, or by increasing
the value of the feedforward capacitor in parallel with the
upper resistor divider resistor.
In Burst Mode operation, the output capacitor stores energy
to satisfy the load current when the LTC3104 is in a low
current sleep state between the burst pulses. It can take
several cycles to respond to a large load step during a sleep
period. If large transient load currents are required then
a larger capacitor can be used at the output to minimize
output voltage droop until the part transitions from Burst
Mode operation to continuous mode operation.
Note that even X5R and X7R type ceramic capacitors have
a DC bias effect which reduces their capacitance when a
DC voltage is applied. It is not uncommon for capacitors
offered in the smallest case sizes to lose more than 50%
of their capacitance when operated near their rated volt-
age. As a result it is sometimes necessary to use a larger
capacitance value or use a higher voltage rating in order to
realize the intended capacitance value. Consult the manu-
facturers data for the capacitor you select to be assured
of having the necessary capacitance in your application.

ensure stability of the loop. If the output capacitance is
too small, the loop crossover frequency will increase to
the point where switching delay and the high frequency
parasitic poles of the error amplifier will degrade the
phase margin. In addition, the wider bandwidth produced
by a small output capacitor will make the loop more sus-
ceptible to switching noise. At the other extreme, if the
