LTM4608
APPLICATIONS INFORMATION
Safety Considerations
The LTM4608 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 LTM4608 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,
including V IN , GND and V OUT . It helps to minimize the
PCB conduction loss and thermal stress.
GND
GND
? Place high frequency ceramic input and output capaci -
tors next to the V IN , GND and V OUT pins to minimize
high frequency noise.
? Place a dedicated power ground layer underneath the
unit.
? To minimize the via conduction loss and reduce module
thermal stress, use multiple vias for interconnection
between top layer and other power layers.
? Do not put vias directly on the pads, unless they are
capped.
? Use a separated SGND ground copper area for com -
ponents connected to signal pins. Connect the SGND
to GND underneath the unit.
Figure 17 gives a good example of the recommended layout.

For easier board layout and PCB assembly due to increased
spacing between land grid pads, please refer to the LTM4608A.
