Safety Considerations
The LTM4613 modules do not provide isolation from V IN
to V OUT . There is no internal fuse. If required, a slow blow
fuse with a rating twice the maximum input current needs
to be provided to protect each unit from catastrophic
failure.
Layout Checklist/Example
The high integration of LTM4613 makes the PCB board
layout very simple and easy. However, to optimize its
electrical and thermal performance, some layout consid-
erations are still necessary.
? Use large PCB copper areas for high current path, in -
cluding V IN , PGND and V OUT . It helps to minimize the
PCB conduction loss and thermal stress.
? Place high frequency ceramic input and output capaci -
tors next to the V D , PGND and V OUT pins to minimize
high frequency noise.
? Use round corners for the PCB copper layer to minimize
the radiated noise.
? To minimize the EMI noise and reduce module thermal
stress, use multiple vias for interconnection between
top layer and other power layers.
? Do not put vias directly on pads.
? If vias are placed onto the pads, the the vias must be
capped.
? Interstitial via placement can also be used if necessary.
? Use a separated SGND ground copper area for com -
ponents connected to signal pins. Connect the SGND
to PGND underneath the unit.
? Place one or more high frequency ceramic capacitors
close to the connection into the system board.
Figure 17 gives a good example of the recommended layout.
? Place a dedicated power ground layer underneath the
unit.
