Input Decoupling Capacitor (C1)
connected as close as possible to the input and ground pin of
the NCP4587. Higher values and lower ESR improves line
transient response.
Output Decoupling Capacitor (C2)
to achieve stable operation of the IC. If tantalum capacitor
is used, and its ESR is high, the loop oscillation may result.
If output capacitor is composed from few ceramic capacitors
in parallel, the operation can be unstable. The capacitor
should be connected as close as possible to the output and
ground pin. Larger values and lower ESR improves dynamic
parameters.

current. These two modes can be selected by AE pin. If AE
pin is at low level Auto ECO mode is available. Please, see
supply current vs. output current charts.
Thermal
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and also the ambient
temperature affect the rate of temperature rise for the part.
That is to say, when the device has good thermal
conductivity through the PCB, the junction temperature will
be relatively low with high power dissipation applications.
PCB layout

capacitors C1 and C2 as close as possible to the IC, and make
wiring as short as possible.
