SQE48T20120 DC-DC Converter
36-75 VDC Input; 12 VDC @ 20 A Output
Preliminary Data Sheet
Ripple and Noise
Figure 1010 shows the output voltage ripple waveform,
measured at full rated load current with a 10F
tantalum and a 1F ceramic capacitor across the
output. Note that all output voltage waveforms are
measured across the 1F ceramic capacitor.
The input reflected-ripple current waveforms are
obtained using the test setup shown in Figure 11 The
corresponding waveforms are shown in Figure 12 and
Figure 13.
