Requirement on Output Load In order to ensure the product operates effi ciently and reliably, make sure the specifi ed 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 specifi ed minimum load, the output ripple may increase sharply while its effi ciency and reliability will reduce greatly. If the actual output power is very small, please add an E appropriate resistor as extra loading. 2. Recommended Circuit The VYB10W series has been tested according to the following recommended testing circuit. This series should be tested under load. (see Figure 1) U Single Output Dual Output Vin 7 3 +Vo Vin 7 3 +Vo Figure 1 Cout N Cin DC/DC Cout Cin DC/DC 2 Cout 0V GND 8 0V GND 8 -Vo 1 1 If you want to further decrease the input/output ripple, you can increase capacIitance 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.
