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