Recommended Circuit All of the VAWQ12 models have been tested according to the following recommended testing circuit before leaving factory. If you want to further decrease the input ripple, Cin is recommended to use 100 μF. If ripple and noise are required, you can increase capacitance of Cout properly. However, the capacitance should not be higher than Max capacitance. (see Figure 1). Figure 1 Vin Vout C in DC DC GND 2. Recommended Capacitance Table 1 Note: 0V Vout (Vdc) Cin (μF) Cout (μF) 3.3/5 100 220 12/15 100 100 1. All specifications measured at Ta: 25°C, humidity <75%, nominal input voltage and rated output load unless otherwise specified 2. When product begins to work, the temperature may rise slowly until the unit is stabilized. It is normal that the output voltage, derating, and efficiency may reduce during this time. 3. Min. load shouldn't be less than 10%, otherwise ripple maybe increased dramatically. If the product operates under min. load may not meet all specifications listed. Operation under minimum load will not damage the converter. cui.com For more information, please visit the product page.
