Boost Capacitors and Gate Drive Lines
Place the boost capacitors (C38, C46) close to their respective pins for maximum transfer of the capacitive energies. Place the gate driver
resistors (R35, R40, R44, R47) close to their respective pins. This limits the switching noise generated. Place the FET gate bleed resistors
(R36, R42, R45, R48) close to their respective FET gate pad/pin.
