The PWA_LT-1W5 & PWB_LT-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);

**Input voltage can’t exceed this value, or will cause the permanent damage.

Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

2) Where isolation is necessary between input

and output (Isolation Voltage ≤1500 VDC);

3) Where the regulation of the output voltage

and the output ripple noise are demanded.

Temperature Derating Graph

If you want to further decrease the input/output

ripple, you can increase capacitance properly or

choose capacitors with low ESR. 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 (Table 1). General:

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 flash startup current of this kind

of DC/DC module (Figure 2)

APPLICATION NOTE

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.

No parallel connection or plug and play.
