Application Note
Recommended Circuit
All the CTDD2210S-S series have been tested according to the following recommended testing circuit
before leaving factory. This series should be tested under load. Never to be tested under no load. (See
figure 1). If you want to further decrease the input/output ripple, you can increase capacitance properly or
choose capacitors with low ESR. However, the capacitance should not be too high. (Table 2). If you want
to use the products in high EMI, please choose our metal packaged prodcts.
