Notes:  
1. For input voltages higher than 30 Vdc, a 22 µF / 50 V input capacitor is required.  
2. Tested at nominal input, 20~100% load, 20 MHz bandwidth, with 10 µF electrolytic and 1 µF ceramic capacitor on the output. At loads below 20%, the max ripple and  
noise of the 3.3 & 5 Vdc outputs will be 100 mVp-p, and the other outputs will be 2% Vo.  
3. Measured at min Vin, full load.  
4. All specifications are measured at Ta=25°C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.

Note:  
1. C1 & C2 (C3 & C4) are required and should be connected as close to the module pins as possible.  
2. To reduce the output ripple further, C2 & C4 can be increased as needed and the use of tantalum or low ESR electrolytic capacitors would be recommended.  
3. When using application circuit in Figure 3, a 10 µH LDM component is recommended to reduce the interference.
