RECOMMENDED CIRCUIT
All the CTDD5025DF-S1K-10M 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). When it is used in
unregulated power supply, be sure that the flucuating range of the power supply adn the rippled voltage do not exceed the
module standard. Input current of power supply should afford the startup current of this kind of DC/DC module. (See figure 2)
