DESIGN CONSIDERATIONS
1) Recommended circuit
All the URF_LP-20W Series have been tested according to the following recommended test circuit before leaving the factory (see Figure 4).
If you want to further decrease the input/output ripple, you can increase a capacitance-values properly or choose capacitors with low ESR, but
the total capacitance of the filter capacitor must not exceed the Max Capacitive Load. The recommended capacitance of its filter capacitor sees
Table 2.

2) 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. Max. Capacitive Load is 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 test methods are based on our corporate standards.
5. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details.
6. Please contact our technical support for any specific requirement.
7. Specifications of this product are subject to changes without prior notice.
