SQE48T20120 DC-DC Converter
36-75 VDC Input; 12 VDC @ 20 A Output
Preliminary Data Sheet
Figure 9. Output voltage response to load current step-
change (10A – 15A – 10A) at Vin = 48 V.
Top trace: output voltage (100mV/div.)
Bottom: load current (5A/div.).
Current slew rate: 0.1 A/s. Time scale: 0.1ms/div.
Co = 10F tantalum + 1F ceramic
Figure 10. Output voltage ripple (50 mV/div.) at full rated
load current into a resistive load with Co = 10F
tantalum + 1F ceramic and Vin =48V. Time scale:
1s/div.
Figure 11. Test setup for measuring input reflected ripple
currents,
ic and is.
Figure 12. Input reflected-ripple current, is (50 mA/div.),
measured through 100 H at the source at full
rated load current and Vin = 48 V. Refer to 11
for test setup. Time scale: 1 s/div.
Figure 13. Input reflected ripple-current, ic (200 mA/div.),
measured at input terminals at full rated load
current and Vin = 48 V. Refer to Figure 11 for
test setup. Time scale: 1 s/div.
