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

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.
