PCB Layout Considerations
1. Place the power MOSFET’s as close to the con-
troller as possible. Failure to do so will cause
large amounts of ringing due to the parasitic
inductance of the copper trace. Additionally, the
parasitic capacitance of the trace will weaken the
effective gate drive. High frequency switching
noise may also couple to other control lines.
2. Always place the by-pass capacitors (0.1F and
1F) as close to the EL7571C as possible. Long
lead lengths will lessen the effectiveness.
3. Separate the power ground (input capacitor
ground and ground connections of the Schottky
diode and the power MOSFET’s) and signal
grounds (ground pins of the by-pass capacitors
and ground terminals of the EL7571C). This will
isolate the highly noisy switching ground from
the very sensitive signal ground.
4. Connect the power and signal grounds at the out-
put capacitors. Output capacitor ground is the
quietest point in the converter and should be
used as the reference ground.
5. The power MOSFET’s output inductor and
Schottky diode should be grouped together to
contain high switching noise in the smallest area.
6. Current sense traces running from pin 11 and pin
12 to the current sense resistor should run paral-
lel and close to each other and be Kelvin
connected (no high current flow). In high current
applications performance can be improved by
connecting low Pass filter (typical values 4.7
,
0.1F) between the sense resistor and the IC
inputs.
