Supply Capacitor: It is recommended to place a bypass capacitor (C
) between the V
and COM pins. A ceramic 1 F
IN
CC
ceramic capacitor is suitable for most applications. This component should be placed as close as possible to the pins in
order to reduce parasitic elements.
Routing and Placement: Power stage PCB parasitic elements can contribute to large negative voltage transients at the
switch node; it is recommended to limit the phase voltage negative transients. In order to avoid such conditions, it is
recommended to 1) minimize the high-side emitter to low-side collector distance, and 2) minimize the low-side emitter to
negative bus rail stray inductance. However, where negative V
spikes remain excessive, further steps may be taken to
S
reduce the spike. This includes placing a resistor (5
or less) between the V
pin and the switch node (see Figure 20),
S
and in some cases using a clamping diode between COM and V
(see Figure 21). See DT04-4 at
