Input current of power supply should afford the startup current of this kind of DC/DC module. (See figure 2) External Capacitor Although this series of DC/DC converter can work without external capacitor, in order to keep an optimum performance, however, it needs external capacitor. (See Table 1) Requirement on Output Load To ensure this module operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (namely full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum out put load is not less than 10% Of the full load, and that this product should never be operated under no load!!! If the actual load is less below the specified minimum load,the output ripple of this type of DC/DC converter will increase drastically and at the same time efficiency & reliability of the circuit will decrease deeply .If the actual output power from the load in your circuit is very small,please connect a resistor with proper resistance at the output end to in parallel to increase the load, or use our company’s other products with a lower rated output power. The products cannot be used in parallel and in plug and play. External Capacitor Table(Table 1) Vin Cin Cout (0+70°C) Cout (-40+85°C) 5V & 12V 100uF 24V & 48V 10uF 100uF (electrolytic capacitor) 47uF (tantalum capacitor) Note: All Pins on a 2.54mm pitch; All Pin diameters are 0.50 mm(Tolerance:±0.25); All dimensions in mm. The dimensions of the WRAP series are correspondent with the WRBP series. APPLICATION NOTE MORNSUN Science& Technology Ltd. Recommended Circuit All the WRA-3W Series have been tested according to the following recommended testing circuit before leaving factory. This series should be tested under load. Never be tested under no load (See Figure 1 & 2). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high.(See table 1).If you want to use the products in high EMI, please choose our metal packaged products. Input Current When it is used in unregulated power supply,be sure that the fluctuating range of the power Address: 8th Floor 8th Building, Huangzhou Industrial District, Guangzhou, China Tel :86-20-85571041 Fax:86-20-85536272 Http:// www.mornsun.cn/ |
