(100 mA/div), measured at input terminals at full rated

load current and Vin = 48 V. Refer to Fig. 1.2V.11 for

test setup. Time scale: 1 µs/div.

(10 mA/div), measured through 10 µH at the source at

Fig. 1.2V.15: Load current (top trace, 20 A/div,

20 ms/div) into a 10 mꢀ 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.

current limit point and converter shutdown point. Input

voltage has almost no effect on current limit

characteristic.
