APPLICATIONCIRCUIT
Based on fast charge/discharge of capacitors,
this circuit involves high di/dt values limited only
by R
on
of switches. This implies a critical layout
design due to the need to minimize inductive
paths and place capacitors as close as possible
to the device.
A good layout design is strongly recommended
for noise reason. For best performance, use very
short connections to the capacitors and the
values shown in table 1.
C3 and C4 must have low ESR in order to
minimize the output ripple. Their values can be
reduced to 2
μ
F and 1
μ
F, respectively, when
using ceramic capacitors, but must be of 10
μ
F or
larger if aluminiumelectrolytic are chosen.
C5 must be placed as close to the device as
possible and could be omitted if very low output
noise performanceare not required.
