Check the stress on the power MOSFET by measuring its
drain-to-source voltage directly across the device terminals
(reference the ground of a single scope probe directly to
the source pad on the PC board). Beware of inductive
ringing, which can exceed the maximum specified voltage
rating of the MOSFET. If this ringing cannot be avoided,
and exceeds the maximum rating of the device, either
choose a higher voltage device or specify an avalanche-
rated power MOSFET.
The small-signal components should be placed away from
high frequency switching nodes. For optimum load regula-
tion and true remote sensing, the top of the output voltage
sensing resistor divider should connect independently to
the top of the output capacitor (Kelvin connection), staying
away from any high dV/dt traces. Place the divider resis-
tors near the LT3757 in order to keep the high impedance
FBX node short.
Figure 11 shows the suggested layout of the 8V to 16V
Input, 24V/2A Output Boost Converter.
