When open or high impedance, converter work well. When control pin positive referenced to the negative input (equal

to import to earth), converter shutdown. Please note that the input current should be between 5-10mA, exeeding the

maximum 20mA will cause permanent damage to converter.

All the CTDD2210SF-D1.5K-2 Series have been tested according to the following recommended testing circuit before leaving factory. This series

should be tested under load. Never 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 (See table 1). If you want to use the

products in high EMI, please choose our metal packaged products.
