3W HIGH POWER WHITE LED DRIVER
PCB Layout Guidelines
As for all switching power supplies, the layout and components placement of the FSP3604 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 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.
