Notes:

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

2. Tested at nominal input, 10~100% load, 20 MHz bandwidth, with 10 µF electrolytic and 1 µF ceramic capacitor on the output. At loads below 10%, the max ripple and

noise of the 3.3 & 5 Vdc outputs will be 150 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.
