frequencies and high load current. Figure 13 shows the
results of the complete system with output capacitor and
compensation network for 45° of phase margin.
Because of the large variety of capacitors, varying ESRs and
PC board layouts, Table 1, based upon system simulations
is provided as a starting point guide to aid in the selection of
compensation networks for output capacitors values of 1

F and 1000
μ
F with ESR values of 5m
, 30m
and 100m
for each capacitor value. The frequencies
associated with the compensation elements are also shown
to aid in component selection.
Parallel capacitors of the same value and type can be
treated as a combination. For example three 100
μ
F, 10m
capacitors may be treated as one 300
μ
F, 3.3m
capacitor.
Mixed capacitors require more attention. For example the
compensation for a 1000
μ
F, low ESR capacitor will suffice
for a shunting 10
μ
F, low ESR capacitor.
