DCP0124
1. To predict the output voltage at 100% load take the mea-
sured or specified voltage at 75% load and multiply by
(1 + Load Reg 75% to 100%). For example a DCP012405P
typical V
OUT
at 100% load will be 5V
x
(1 – 4%) = 4.8V.
2. To predict the output voltage at 10% load take the mea-
sured or specified voltage at 75% load and multiply by
(1 + Load Reg 10% to 75%). For example a DCP012405P
typical V
OUT
at 10% load will be 5V
x
(1 + 9%) = 5.4V.
3. To predict the output voltage at 25% load on higher V
OUT
versions take the measured or specified voltage at 75%
load and multiply by (1 + Load Reg 25% to 75%). For
example a DCP012415DP typical +V
OUT
at 25% load will
be 12V
x
(1 + 8%) = 13.0V. To then estimate the voltage
at 10% load take the previously calculated +V
OUT
at
25% load and multiply by (1 + Load Reg 10% to 25%).
In this case the typical +V
OUT
at 10% load will be 13.0V
x
(1 + 11%) = 14.4V.
To obtain predictions for loads other than those specified
assume the V
OUT
versus load characteristic is linear between
the load points and calculate accordingly. The 10% to 100%
load specification guarantees the maximum voltage excursion
for any load between 10% to 100% with respect to V
OUT
at
75% load.
The above does not take into consideration line regulation and
assumes a nominal input voltage. The 1:1 line regulation of the
DCP01 family means that a percentage change in the input
will give a corresponding percentage change in the output.
Connecting the DCP0124 in Series
Multiple DCP01 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 DCP01’s galvanic isolation.
Connect the positive V
OUT
from one DCP01 to the negative
V
OUT
(0V) of another (see Figure 5). If the SYNC
IN
pins are
tied together, the self-synchronization feature of the DCP01
will prevent beat frequencies on the voltage rails. The SYNC
feature of the DCP01 allows easy series connection without
external filtering which is necessary in competing solutions.
The outputs on dual output DCP01 versions can also be
connected in series to provide 2 times the magnitude of
V
OUT
(see Figure 6). For example, a dual 15V DCP012415D
could be connected to provide a 30V rail.
Connecting the DCP0124 in Parallel
If the output power from one DCP0124 is not sufficient, it
is possible to parallel the outputs of multiple DCP01s (see
Figure 7). Again, the SYNC feature allows easy synchroni-
zation to prevent power-rail beat frequencies at no additional
filtering cost.
