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 will be 150 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:
8. C1 & C2 are required and should be connected as close to the module pins as possible.
9. C1 & C2 can be increased as needed and the use of tantalum or low ESR electrolytic capacitors would be recommended.
10. To reduce the output ripple further, it is recommended to add an “LC” filter at the output (see figure 2) with a 10~47 µH L component.
