Fig. 13: Input reflected ripple current, ic (500 mA/div.), measured at
input terminals at full rated load current and Vin = 48 V. Refer to
Fig. 12 for test setup. Time scale: 1 µs/div
Fig. 14: Input reflected ripple current, is (10 mA/div.), measured
through 10 µH at the source at full rated load current and Vin = 48
V. Refer to Fig. 12 for test setup. Time scale: 1 µs/div
Fig. 15: Output voltage vs. load current showing current limit point
and converter shutdown point. Input voltage has almost no effect
on current limit characteristic
Fig. 16: Load current (top trace, 20 A/div., 50 ms/div.) into a 10 m
Ω
short circuit during restart, at Vin = 48 V. Bottom trace (20 A/div.,
2ms/div.) is an expansion of the on-time portion of the top trace
