36-75 VDC Input; 3.3 VDC @ 20A Output
Figure 11. Output voltage response to load current step
change (10A – 15A – 10A) at Vin = 48 V.
Top trace: output voltage (50mV/div.)
Bottom: load current (5 A/div.).
Current slew rate: 0.1 A/μs. Time scale: 200 μs /div.
Co = 10μF tantalum + 1μF ceramic
Figure 12. Output voltage response to load current step
change (10A – 15A – 10A) at Vin = 48 V.
Top trace: output voltage (50mV/div.)
Bottom: load current (5 A/div.).
Current slew rate: 1 A/μs. Time scale: 200 μs /div.
Co = 470μF POS + 1μF ceramic
Figure 13. Output voltage ripple (20 mV/div.) at full rated
Figure 14. Input reflected-ripple current, i s (10 mA/div.),
measured through 10 μH at the source at full rated
load current and Vin = 48 V. Refer to Fig. J for test
setup. Time scale: 1 μs/div.
Figure 15. Input reflected ripple-current, i c (100 mA/div.),
measured at input terminals at full rated load
current and Vin = 48 V. Refer to Fig. J for test setup.
Time scale: 1 μs/div.
Figure 16. Load current (top trace, 20 A/div., 100 ms/div.) into
load current into a resistive load with Co = 10μF
a 10 m ?
short circuit during restart, at
tantalum + 1μF ceramic and Vin = 48V. Time
scale: 1μs/div.
Vin = 48 V. Bottom trace (20 A/div., 5 ms/div.) is an
expansion of the on-time portion of the top trace.
