PRODUCTION DATA
If DPWMs travel for a longer distance than 3 inches from the control card to a main power stage, a Schottky clamping diode may be needed as shown in Figure 12-4to prevent electrical overstress on the device during lightning test. The long trace may also pick up the noise from other switching sources. Avoid DPWM signals to cross switching nodes.
