Layout Considerations
Careful attention must be paid to the PCB board
layout and components placement. Proper layout
of the high frequency switching path is critical to
prevent noise and electromagnetic interference
problems. The loop of MP3305 SW to GND pin,
output diode, and output capacitor is flowing with
high frequency ripple current, it must be as short
as possible.
The IN pin of the IC must be locally bypassed. A
RC filter is highly recommended for eliminating
the noise on IN pin. It could be implemented as
shown in Figure 3.
