Layout recommendations
A proper printed circuit board layout is very important for the correct operation of any switch-
mode converter. Placing components carefully, routing traces correctly, appropriate trace
widths and compliance with isolation distances are very important matters. In particular:
• The compensation network should be connected as closer as possible to the COMP
pin, keeping short the trace for the GND
• Signal ground should be routed separately from power ground, as well as from the
sense resistor trace
