These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range: 2:1); 2) Where isolation is necessary between input and output (Isolation Voltage≤1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

This series should be tested under load(Figure 1). Vin Vout Cin DC DC 0V GND If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR.

APPLICATION NOTE Output Load In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% full load, If the actual load is less than the specified minimum load, the output ripple may increase sharply. If the actual output power is very small, please add an appropriate resistor as extra loading,or contact our company for other lower output power products.
