from the input power supply in a distributed

power supply system on a circuit board. These

products apply to:

2) Where isolation is necessary between input

and output (Isolation Voltage≤ 1000VDC);

3)Where isolation is necessary between Vout1

and Vout2 (Isolation Voltage≤ 1000VDC);

4) Where the regulation of the output voltage

and the output ripple noise are demanded.

APPLICATION NOTE

1) CS Pin

By connecting a low ESR capacitor between this terminal and the

pin-7(Figure 1), the output ripple and noise may be further improved.

Generally, the capacitance is no greater than 47uF.

2) Requirement on Output Load

To ensure this module can operate efficiently and reliably, During operation,

the minimum output load is not less than 10% of the full load, If the actual

load is less than the specified minimum load, the output ripple may

increase sharply. 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.

EXTERNAL CAPACITOR TABLE (TABLE 1)

3) Recommended Circuit

If you want to further decrease the input/output ripple, you can increase

capacitance properly or choose capacitors with low ESR (Figure 1).

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)

4) Input current

When the environment temperature is higher than 71°C, the product

output power should be less than 60% of the rated power.

While using unstable power source, please ensure the output voltage and

ripple voltage do not exceed indexes of the converter. The preceding power

source must be able to provide for converter sufficient starting current Ip

(Figure 2). General: Ip ≤1.4*Iin-max

5) 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 damage 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.

4. In this datasheet, all the test methods of indications are based on corporate standards.

5. Only typical models listed, other models may be different, please contact our technical person for more details.
