These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) Where isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.

Operating Temp.(oC) TYPICAL CHARACTERISTICS Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 10% of the full load, and that this product should never be operated under no load! If the actual output power is very small, please RECOMMENDED CIRCUIT L +Vo L Vin Cin GND DC DC Cout 0V connect a resistor with proper resistance at the output end in parallel to increase the load. (Figure 1) Recommended circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be c...
