Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically. Operation under 10% load will not damage the converter; However, they may not meet all specification listed .

APPLICATIONS

The WRD_S-1W Series are specially designed for applications where a wide range input voltage power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. 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 bet ween input and output & Vout1 and Vout2 (Isolation Voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

Generally, the capacitance is no greater than 47uF. Requirement on Output Load To ensure this module can operate efficiently and relia bly, During operation, the minimum output load is not less than 10% of the 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 re sistor as extra loading, or contact our company for other lower output power products. Recommended Circuit If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR (Figure 1). +Vo1 0V1 Co Ci Vin GND Cs Li +Vo2 0V2 Co CS +Vo2 4.7-12uH (Figure 1) However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, th e greatest capacitance of its filter capacitor sees (Table 1)Cin： 5V & 12V 100 μF 24V & 48V 10 μF-47μF Lin ： 10 μH-120μH Cout：100μF(TYP) Extemal Capacitor Table(Table 1) Vout(VDC) 2W:Cout(uF) 1W:Cout(uF) 5 680 470 9 470 330 12 330 220 15 220 100 Input current While using unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter.
