## **MODEL** 

- Notes: 1. For input voltages higher than 30 Vdc, a 22 µF / 50 V input capacitor is required. 

2. Tested at nominal input, 30~100% load for 3.3 Vdc model, 20 MHz bandwidth. 

At loads below 30%, the max ripple and noise of the 3.3 Vdc output will be 200 mVp-p, and a load below 20% for the other outputs the levels increase to 250 mVp-p.. 

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.   The required C1 and C2 capacitors must be connected as close as possible to the terminals of the module. 

   2.   Refer to Table 1 for C1 and C2 capacitor values. For certain applications, increased values and/or tantalum or low ESR electrolytic capacitors may also be used instead. 

   3.   Converter cannot be used for hot swap or with output in parallel. 

   4.   To further reduce the output ripple and noise, we suggested the use of a “LC” filter at the output terminals, with an inductor value (L) of 10µH-47µH.
