PCB Layout Guidelines
As for all switching power supplies, the layout
and components placement of the PAM2801 is
an important step in the design; especially at
high peak currents and high switching
frequencies.
The input capacitor and output capacitor should
be placed respectively as close as possible to
PAM2801
1W High Power White LED Driver
the input pin and output pin of the IC; the inductor
and schottky diode should be placed as close as
possible to the switch pin by using wide and short
traces for the main current path; the current
sense resistor should be placed as close as
possible between the ground pin and feedback
pin.
