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 & Vout1 and Vout2 (Isolation Voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

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 .

Max 95 85 125 °C Units % APPLICATION NOTE CS Pin By connecting a low ESR capacitor between this terminal and the pin-7(Figure 1), the output ripple and noise may be further improved. Generally, the capacitance is no greater than 47uF. 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, 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. Recommended Circuit If you want to further input/output ripple, you Note: 1. All specifications measured at TA=25°C, humidity
