PCB Layout Information

Good printed circuit board layout techniques are

important to any switching circuitry and switching

power supplies are no different. When wiring the

switching high current paths, short and wide traces

should be used. Therefore, it is important that the input

and output capacitors be placed as close as possible to

the MCP1623/24 to minimize the loop area.

The feedback resistors and feedback signal should be

routed away from the switching node and the switching

current loop. When possible, ground planes and traces

should be used to help shield the feedback signal and

minimize noise and magnetic interference.
