APPLICATIONS
The IB_LS(D)-1W Series are
specially designed for applications
where a single power supply is highly
isolated from the input power supply in
a distributed power supply system on
a circuit board.
These products apply to:
1) Where the voltage of the input
power supply is fixed (voltage
variation ≤±5%);
2) Where isolation is necessary
between input and output (isolation
voltage =1000VDC);
3) Where the regulation of the output
voltage and the output ripple and
noise are demanded.

Filtering
In some circuits which are sensitive to noise and
ripple, a filtering capacitor may be added to the
DC/DC output end and input end to reduce the noise
and ripple. However, the capacitance of the output
filter capacitor must proper. If the capacitance is too
big, a startup problem might arise. For every
channel of output, providing the safe and reliable
operation is ensured, the greatest capacitance of its
filter capacitor refer to the EXTERNAL CAPACITOR
TABLE. To get an extreme low ripple, an LC
filtering network may be connected to the input and
output ends of the DC/DC converter, which may
produce a more significant filtering effect. It should
also be noted that the inductance and the frequency
of the LCfiltering network should be staggered
with the DC/DC frequency to avoid mutual
interference (Figure 1).

Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection against
over-current and short-circuits. The simplest method
is to connect a self-recovery fuse in series at the
input end or add a circuit breaker to the circuit.
When the environment temperature is
higher than 70°C, the product output power
should be less then 60% of the rated power.
. Note: All Pins on a 2.54mm(0.1) pitch; All Pin diameters are 0.50 mm(0.02);
Tolerances:±0.25mm(0.01); Unit: mm(inch).
APPLICATION NOTE
Requirement On Output Load
To ensure this module can operate efficiently and reliably, a minimum load is specified for
this kind of DC/DC converter in addition to a maximum load (namely full load). During
operation, make sure the specified range of input voltage is not exceeded, the minimum
output load is not less than 10% of the full load, and that this product should never be
operated under no load! If the actual output power is very small, please connect a resistor
with proper resistance at the output end in parallel to increase the load, or use our
comwpwanwys. pDroadtuactsS whietheatl4owUer. craotemd output power.
