Efficiency Vs Input voltage WRA2412YMD-15W 的 APPLICATION NOTE Efficiency VS Input voltage Recommended circuit All the WRA_YMD-15W&WRB_YMD-15W Series have been tested according to the following recommended testing circuit before leaving factory . This series should be tested under load. Never be test ed under no load (see Figure 1). 3. Efficiency Vs Output Power WRA2412YMD-15W If you want to further decrease the output ripple, you can increase capacitance properly or choose Efficiency VS Output load capacitors with low ESR. However, the capacitance can't exceed the maximum capacitor load in the list. Recommended capacitance To ensure these series can operate efficiently and reliably, the recommended capacitance of input and output sees the below table.
