DESIGN & APPLY CONSIDERATIONS

1) Requirement on output load

To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of the full

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.

2) Overload Protection

Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is add a circuit

breaker to the circuit.

3) Recommended circuit

All the PWA_(C)D-10W & PWB_(C)D-10W series have been tested according to the following recommended testing circuit before leaving factory.

(see Figure 3).

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 must less than the Max. Capacitive Load.

4) CTRL Terminal

When open or high impedance, the converter work well; When this pin is ‘high level’; the converter shutdown; It should be note that the input

current should between 5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The value of R can be derived as

follows:

V_C- V_D- 1.0

R =

I_C

5) Input current

Nominal input voltage range. The input current of the power supply must be sufficient to the startup current (Ip) of the DC/DC module (Figure 4).

General: Ip ≤1.6*Iin-max

(Figure 4)

6) No parallel connection or plug and play

Note:

1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically. Operation under minimum load will not damage the converter;

However, they may not meet all specification listed.

2. Max. Capacitive Load tested at input voltage range and full load.

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.

6. Our company offer custom products.

7. Specifications subject to change without notice.
