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 load), a minimum range of the input voltage actual sharply power load load while is for is not exceeded, is its very is specified less than efficiency small, the minimum output the specified minimum and please this kind of DC/DC converter. Make reliability add an will load no load, reduce appropriate less the than 10% output greatly. resistor as If load. If ripple may increase the extra full sure the specified actual loading, output or contact our company for other lower output power products. 2) Recommended Circuit All the WRE_YD-6W & WRF_YD-6W following recommended testing circuit before Series leaving have been tested according to the factory. This series should be tested under load. Never be tested under no load (see Figure 1). want to capacitance properly If you or further choose output filter capacitor must might arise. For ensured, the every be decrease the capacitors with proper. If channel of the output, low input/output ripple, you ESR. However, the capacitance provided is the too safe big, and can increase capacitance a startup reliable of the problem operation is greatest capacitance of its filter capacitor sees (Table 1).
