current limit point and converter shutdown point. Input
voltage has almost no effect on current limit
characteristic.
Fig. 3.3V.15: Load current (top trace, 20 A/div,
20 ms/div) into a 10 m ? short circuit during restart, at
Vin = 48 V. Bottom trace (20 A/div, 1 ms/div) is an
expansion of the on-time portion of the top trace.
