SC33020H

is related to the PCB stray inductance and the placement
of the capacitors. The input capacitor C and output
capacitor C2 need to be placed close to the SC33020H. It
is important to keep the voltage ringing below the
maximum voltage rating of the SC33020H.
Evaluation Board Information
The Top Layer and Bottom Layer of a standard evaluation
board are shown in Fig. 3 and Fig. 4, respectively.
Both T and T2 test points are Kelvin connections which
can be used to minimize the measurement error of R
ON.
To enable the part, a jumper can be used between VIN
and EN on J. To disable the part, a jumper can be con-
nected between EN and GND on J. C3 is an optional
solution to improve ringing at input rail during turn-off
and reverse blocking conditions.
