Supply Capacitor: It is recommended to place a bypass capacitor (C
) between the V
and V
pins. A

ceramic 1 μF 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
as 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,
S
further steps may be taken to reduce the spike. This includes placing a resistor (5 Ω or less) between the V
pin
S
and the switch node (see Figure 10), and in some cases using a clamping diode between V
and V
(see Figure
