ADDITIONAL FUNCTIONS
Connecting the DCP02 in Series
DISABLE/ENABLE
The DCP02 can be disabled or enabled by driving
the SYNC pin using an open drain CMOS gate. If the
SYNC pin is pulled low, the DCP02 will be disabled.
The disable time depends upon the external loading;
the internal disable function is implemented in 2
μ
s.
Removal of the pull down causes the DCP02 to be
enabled.

SBVS011E–MARCH 2000–REVISED AUGUST 2006Multiple DCP02 isolated 2W DC/DC converters can
be connected in series to provide nonstandard
voltage rails. This configuration is possible by using
the floating outputs provided by the galvanic isolation
of the DCP02.
Connect the positive V
from one DCP02 to the
negative V
OUT
(0V) of another (see
Figure 7
). If the
SYNC pins are tied together, the self-synchronization
feature of the DCP02 prevents beat frequencies on
the voltage rails. The SYNC feature of the DCP02
allows

filtering, thus minimizing cost.
Capacitive loading on the SYNC pin should be
minimized in order to prevent a reduction in the
oscillator frequency.

The outputs on the dual-output DCP02 versions can
also be connected in series to provide two times the
magnitude of V
, as shown in
Figure 8
. For

The high switching frequency of 400kHz allows
simple filtering. To reduce ripple, it is recommended
that a 1

F capacitor be used on V
. Dual outputs
should both be decoupled to pin 5. A 2.2

on the input is also recommended.
