3) Ctrl Terminal

When open or high impedance, the converter works well; When this pin is

‘high’, the converter shut down. It should be note that the input current

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

4) 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 average current of this kind of DC/DC module (Figure 7).

5) It is not recommended to increase the output power capability by connecting two or more converters in parallel. The product is not

hot-swappable

Note:

1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically. If the product operates under min. load, it may not be

guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter.

2. Recommended Dual output models unbalanced load is

≤±5%, if the product operates >±5%, it may not be guaranteed to meet all specifications

listed. Please contact our technical support for more details.

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

4. All specifications measured at Ta=25

°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

5. In this datasheet, all test methods are based on our corporate standards.

6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details.

7. Please contact our technical support for any specific requirement.

8. Specifications of this product are subject to changes without prior notice.
