MP3209 – 1.4MHZ, 350mA BOOST CONVERTER
LAYOUT CONSIDERATIONS
High frequency switching regulators require
very careful layout for stable operation and low
noise. All components must be placed as close
to the IC as possible. Keep the path between
MP3209, D1, and C2 extremely short for
minimal noise and ringing. C1 must be placed
close to the IN pin for best decoupling. All
feedback components must be kept close to the
FB pin to prevent noise injection on the FB pin
trace. The ground return of C1 and C2 should
be tied close to the GND pin. See the MP3209
demo board layout for reference.
