RECOMMENDED CIRCUIT APPLICATION NOTE 1) Requirement On Output Load In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra loading, or contact our company for other lower output power products. 2) Recommended Circuit All the WRE_YD-6W&WRF_YD-6W 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). 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 sees (Table 1). General: General: Cin: 5V&12V 100µF 24V&48V 10µF-47µF Cout: 10µF/100mA 3) 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 startup current of this kind of DC/DC module(See figure 2), General: Ip ≤1.4*Iin-max 4) No parallel connection or plug and play http://www.microdc.cn EXTERNAL CAPACITOR TABLE (TABLE 1) Output External Capacitor Table (Table 1) Single Vout Cout Dual Vout (VDC) (uF) (VDC) (uF) 5 1000 ±5 680 12 470 ±12 330 15 330 ±15 220 Technical Enquiries-Email:[email protected] Tel:0086-20-86000646 Cout Page 2 of 3 WRE-YD-6W&WRF-YD-6W Series OUTLINE DIMENSIONS ＆ FOOTPRINT DETAILS MECHANICAL DIMENSIONS RECOMMENDED FOOTPRINT(TOP VIEW) TUBE OUTLINE DIMENSIONS RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C for 10 seconds.
