Fig. 25: Output voltage vs. load current showing current limit
point and converter shutdown point. Input voltage has almost
no effect on current limit characteristic.
Fig. 26: Load current (top trace, 20 A/div, 20 ms/div) into a 10
m Ω 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.
