ISOLATED DC/DC CONVERTERS

48 V Input

3.3 V/50 A, 5.0 V/30 A Output

Ripple and Noise Waveforms

Ripple and noise at full load 3.3 V/50 A output

Ripple and noise at full load 5.0 V/30 A output

Note:

Ripple and noise at 48 V input, with a 1 uF ceramic capacitor and a 10 uF tantalum capacitor at the output

and Ta=25 deg C,.

Transient Response Waveforms

Vout=3.3 V, 50% to 75% Load Transients

Vout=3.3 V, 75% to 50% Load Transients

Vout=5.0 V, 50% to 75% Load Transients

Vout=5.0 V, 75% to 50% Load Transients

Note:

Transient Response is tested at di/dt=0.1 A/us (Vo=3.3 V), di/dt=0.5 A/us (Vo=5.0 V), Vin=48 V, Ta=25°C,

with a 1 µF ceramic capacitor and a 10 µF tantalum capacitor at the output.
