DCP0105
Connecting the DCP0105 in Parallel
If the output power from one DCP0105 is not sufficient, it
is possible to parallel the outputs of multiple DCP0105s (see
Figure 6). Again, the SYNC feature allows easy synchroni-
zation to prevent power-rail beat frequencies at no additional
filtering cost.
THERMAL MANAGEMENT LAYOUT
To maximize the thermal performance of the DCP0105,
taking more care in the PCB layout can provide the most
efficient thermal dissipation paths from the DC/DC. The
input controller IC and the rectifier diodes inside the DCP0105
are bonded directly onto the internal leadframe. The
leadframe, being almost 100% copper, provides an excellent
path for dissipated heat and does so significantly more
efficiently than FR4 PCBs or ceramic substrates found in
alternate packing technology DC/DCs.
Connecting the DCP0105 in Series
Multiple DCP0105 isolated 1W DC/DC converters can be
connected in series to provide non-standard voltage rails.
This is possible by utilizing the floating outputs provided by
the DCP0105’s galvanic isolation.
Connect the positive V
OUT
from one DCP0105 to the nega-
tive V
OUT
(0V) of another (see Figure 4). If the SYNC
IN
pins
are tied together, the self-synchronization feature of the
DCP0105 will prevent beat frequencies on the voltage rails.
The SYNC feature of the DCP0105 allows easy series
connection without external filtering which is necessary in
competing solutions.
The outputs on dual output DCP0105 versions can also be
connected in series to provide 2 times the magnitude of
V
OUT
(see Figure 5). For example, a dual 12V DCP010512DP
could be connected to provide a 24V rail.
