APPLICATIONS
The PWA_(M)D-1W5 & PWB_(M)D-1W5 series
are specially designed for applications where a
wide range input voltage power supplies are
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 wide range (voltage range≤ 4:1);
2) Where isolation is necessary between input
and output (Isolation Voltage≤1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

APPLICATION NOTE
1) Requirement On Output Load
In order to ensure the product operate efficiently and reliably, in addition to a max load
(namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the
specified range of input voltage is not exceeded, the minimum output load no less than 10%
load. If the actual load is less than the specified minimum load, the output ripple may increase
sharply while its efficiency and reliability will reduce greatly. If the actual output power is very
small, please add an appropriate resistor as extra loading, or contact our company for other
lower output power products.

2) Recommended Circuit
All the PWA_(M)D-1W5 & PWB_(M)D-1W5 Series have been tested according to the
following recommended testing circuit before leaving factory. (See Figure 1).
If you want to further decrease the input/output ripple, you can increase capacitance properly
or choose capacitors with low ESR. However, the capacitance should not be too high, or may
cause start-up problem. For every channel of output, provided the safe and reliable operation is
ensured, the greatest capacitance of its filter capacitor sees (Table 1).If you want to use the
products in high EMI, please choose our metal packaged products (PWA_MD-1W5 &
PWB_MD- 1W5). General:

3) Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed the module standard. Input current of power
supply should afford the startup current of this kind of DC/DC module. (See figure 2)
General: Ip
≤1.4*Iin-max
4) No parallel connection or plug and play

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not dam age the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
