5.0 Layout
TP2 (U1-S)
TP1 (U1-D)
Fig.5.1. Board size: L90mm x W37mm x H28mm
Test points TP2 (U1 SOURCE) and TP1 (U1 DRAIN) are provided for ease of monitoring Vds.
TP1 jumper can be replaced with a longer one to allow a current probe insertion for Id monitoring.
For the drain-to-source voltage waveforms, connect the high voltage probe tip to TP1 and the probe
ground to test point TP2.
For switching current waveforms, replace jumper TP1 with a wire loop and use a Tektronix A6302
current probe and AM503 current probe amplifier (with TM501 power module) or equivalent.
