Efficiency Vs Input voltage WRA2412ZMD-15W APPLICATION NOTE Efficiency VS Input voltage Recommended circuit All the WRA_ZMD-15W&WRB_ZMD-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 If you want to further decrease the output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance can't exceed the maximum capacitor load in the list. WRA2412ZMD-15W Efficiency VS Output load Recommended capacitance To ensure these series can operate efficiently and reliably, the recommended capacitance of input and output sees the below table.
