CUI Inc │ SERIES: VYB15W │ DESCRIPTION: DC-DC CONVERTER date 08/29/2012 │ page 5 of 6 APPLICATION NOTES Requirement on Output Load In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded and the minimum output load is not 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. 2. Recommended Circuit The VYB15W series has been tested according to the following recommended testing circuit. This series should be tested under load. (see Figure 1) Single Output DC +Vo C out C in 0V G ND DC DC U DC Cin Cout 0V C out GND N Figure 1 Dual Output Vin +Vo Vin ED 1. -Vo If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. If the capacitance is too big, a startup problem might arise. The maximum allowable capacitance to ensure safe and reliable operation is listed in Table 1.
