Note:
1. Ripple & Noise measured with 20 MHz bandwidth. Load condition: 10% ~ 100%, output noise arise when load is under 10%.
2. Tested by minimal Vin and constant resistive load.
3. Measured input reflected ripple current with a simulated source inductance of 12 µH.
4. Input filter components (C1, C2, L) are used to help meet conducted emissions requirement for the module. These components
should be mounted as close as possible to the module; and all leads should be minimized to decrease radiated noise.
5. An external filter capacitor is required if the module has to meet EN61000-4-4.
Recommended filter capacitor: Nippon Chemicon KY series, 470 µF / 100V.
6. Do not operate the units exceeding the absolute maximum rating, over rating causes damage to the units.
7. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
