Fig. 2.5V.13: Output voltage vs. load current showing cur-
rent limit point and converter shutdown point. Input voltage
has almost no effect on current limit characteristic.
Fig. 2.5V.14: Input reflected ripple current,
ic (100 mA/div),
measured at input terminals at full rated load current and Vin
= 48 V. Refer to Fig. 2.5V.11 for test setup. Time scale: 1
μs/div.
Fig. 2.5V.15: Load current (top trace, 20 A/div, 20 ms/div)
into a 10 m
Ω short circuit during restart, at Vin = 48 V. Bot-
tom trace (20 A/div, 1 ms/div) is an expansion of the on-time
portion of the top trace.
