APPLICATIONS
The E_S/D-1W Series are specially designed
for applications where a group of polar power
supplies are isolated from the input power
supply in a distributed power supply system
on a circuit board.

Note: The E_S/D-0.25W series also are available in our company.
These products apply to:
1) Where the voltage of the input power
COMMON SPECIFICATIONS
supply is fixed (voltage variation ≤±10%);
2) Where isolation is necessary between input
and output (isolation voltage =3000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not
demanding.

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.

OUTLINE DIMENSIONS& RECONMENDED FOOTPRINT DETAILS
Output Voltage Regulation and
Over-voltage Protection Circuit
The simplest device for output voltage
regulation, over-voltage and over-current
protection is a linear voltage regulator with
overheat protection that is connected to
the input or output end in series (see
Figure 2).

APPLICATION NOTE
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 be proper. If
the capacitance is too big, a startup problem might arise. For every channel of
output, provided the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor sees the external capacitor table. To get an
extremely 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 “LC” filtering network should be staggered with the DC/DC
frequency to avoid mutual interference (see Figure 1).
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
company’s products with a lower rated output power (E_S/D -0.25W series).

E0505S-1W,EXXXXS-1W SERIES
The ExxxxS-1W series of industrial temperature range DC/DC converters are the standard building blocks for on-board distributed power systems. They are ideally suited for providing dual rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1 watt.
MICRODC
E0505S-2W,EXXXXS-2W SERIES
The ExxxxS -2W series of industrial temperature range DC/DC converters are the standard building blocks for on-board point-of-use power systems. They are ideally suited for providing dual rail supplies on single rail boards with the added benefit of galvanic isolation to reduce circuit noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 2 watts. Pin compatibility with the ExxxxS-1W series ensures minimal effort in upgrading distributed power systems.
