2. EMC typical recommended circuit (CLASS B) Note: 1.15V/ 24V input series is subject to CY (CY: 1 nF/2KV). 2. It is not needed to add the component in the peripheral circuit when parameter with the symbol of"--". 3. Output load requirements In order to ensure the converter can work reliably with high efficiency, the minimum load should not less than 10% rated load when it is used. If the needed power is indeed small, please parallel a resistor on the output side ( The sum of the efficient power and resistor consumption power is not less than 10%). 4. For more information please find the application...
