LAYOUT CONSIDERATIONS
Layout is important for all switching regulators but is
particularly important for regulators with high switching
frequencies. To achieve high efficiency, proper regulation,
stability, and low noise, a well designed PCB layout is required.
Follow these guidelines when designing PCBs:
•
Keep high current loops as short and wide as possible.
•
Keep the input bypass capacitors close to the PVIN1,
PVIN2, and PVINSYS pins.
•
Keep the inductor and output capacitor close to SW1
and PGND1.
•
Route the VFB2P and VFB2N LDO sense traces side by
side connecting them each as close as possible to the point
of load. Keep them as short as possible and away from
noise sources.
•
Place the frequency setting resistor close to the RT pin.
Keep AGND1 and PGND1 separate on the top layer of the
board. This separation avoids pollution of AGND1 with
switching noise. Do not connect PGND1 to the EPAD on
the top layer of the layout. Connect both AGND1 and
PGND1 to the board ground plane with vias. Ideally,
connect PGND1 to the plane at a point between the input
and output capacitors.
•
Connect the negative terminal of CVBUF to the VFB2N pin.
