10.1 Layout Guidelines
Due to the high power density of these devices, provide ground planes on the input and output rails.
Figure 40 shows the schematic for a single output DCPA1 device. Figure 40 illustrates a printed circuit board (PCB) layout for the schematics.
Including input power and ground planes provides a low-impedance path for the input power. For the output, the COM signal connects via a ground plane, while the connections for the positive and negative voltage outputs conduct via wide traces in order to minimize losses.
The output should be taken from the device using ground and power planes, thereby ensuring minimum losses.
The location of the decoupling capacitors in close proximity to their respective pins ensures low losses due to the effects of stray inductance, thus improving the ripple performance. This location is of particular importance to the input decoupling capacitor, because this capacitor supplies the transient current associated with the fast switching waveforms of the power drive circuits.
If the SYNCIN pin is unused, it is recommended to connect this pin to the input side common, –VS. Allow the SWOUT pin, to remain configured as a floating pad.
