Note:  
1. For input voltage exceeding 30 VDC, an input capacitor of 22uF/50V is required  
2. 20MHz bandwidth, nominal input, 20%-100% load. With light loads at or below 20%, ripple and noise for 3/3V/5V output parts increases to 100mVp-p and for  
9V/12V/15V output parts to 2%Vo max.

Note:  
1. C1 & C2 (C3 & C4) are required and should be connected as close to the module pins as possible.  
2. Refer to Table 1 for C1 and C2 (C3 and C4) capacitor values. For certain applications, increased values for C2 and C4 and/or tantalum or low ESR electrolytic capacitors  
may also be used instead;  
3. When using configurations as shown in figure 3, we recommended to add an inductor (LDM) with a value of up to 10μH which helps reducing mutual interference;  
4. Converter cannot be used for hot swap and with output in parallel.
