DCP0115
1. To predict the output voltage at 100% load take the measured
or specified voltage at 75% load and multiply by
(1 + Load Reg 75% to 100%). For example a DCP011512DP
typical +V
OUT
at 100% load will be 12V
x
(1 – 7%) = 11.2V.
2. To predict the output voltage at 25% load take the measured
or specified voltage at 75% load and multiply by
(1 + Load Reg 25% to 75%). For example a DCP011512DP
typical +V
OUT
at 25% load will be 12V
x
(1 + 5%) = 12.6V.
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 12.6V
x
(1 + 10%) = 13.9V.
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 DCP0115 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. For example, the output on
dual output DCP01 versions can be connected in series to
provide 2 times the magnitude of V
OUT
(see Figure 5). In this
example, a dual 12V DCP011512D is connected to provide
a 24V rail.
Connecting the DCP0115 in Parallel
If the output power from one DCP0115 is not sufficient, it
is possible to parallel the outputs of multiple DCP0115s (see
Figure 6). Again, the SYNC feature allows easy synchroni-
zation to prevent power-rail beat frequencies at no additional
filtering cost.
