36-75 VDC Input; 1.0-12 VDC Output
Fig.
(10 mA/div.), measured through 10 µH at the source at
full rated load current and Vin = 48 V. Refer to
Fig. 2.0V.14 for test setup. Time scale: 1 µs/div.
Fig. 2.0V.18: Load current (top trace, 20 A/div.,
20 ms/div.) into a 10 mΩ 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.
