1. Output load requirement

To ensure this module can operate efciently and reliably, the minimum output load may not be less than 5% of the full load during

operation. If the actual output power is low, connect a resistor at the output end in parallel to increase the load.

2. Recommended circuit

This series has been tested according to the following recommended testing circuit before leaving the factory. This series should

be tested under load (see Figure 3 and Table 3). If you want to further decrease the input/output ripple, you can increase the

capacitance accordingly or choose capacitors with low ESR. However, the capacitance of the output lter capacitor must be

appropriate. If the capacitance is too high, a startup problem might arise. For every channel of the output, to ensure safe and reliable

operation, the maximum capacitance must be less than the maximum capacitive load (see Table 4).

3. CTRL Terminal

When open or applied high impedance, the converter will turn on. When it’s pulled high, the converter will shutdown. The input

current should between 5~10mA. Exceeding the maximum 20mA will cause permanent damage to the converter. The value for R can

be derived as follows:

4. Input Current

When it is used in an unregulated condition, make sure that the input uctuations and ripple voltage do not exceed the module

standard. Refer to Figure 5 and Table 5 for the startup current of this dc-dc module.

Note: 1. Minimum load shouldn't be less than 5%, otherwise ripple may increase dramatically. Operation under minimum load will not damage the converter, however, they may

not meet all specications listed.

2. Maximum capacitive load is tested at input voltage range and full load.

3. All specications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specied.
