Vo Startup
Fig. 7: Turn-on transient at full rated load current
(resistive) with no output capacitor at Vin = 48 V,
triggered via ON/OFF pin. Top trace: ON/OFF signal
(5 V/div.). Bottom trace: output voltage (5 V/div.).
Time scale: 5 ms/div.
Fig. 8: Turn-on transient at full rated load current
(resistive) plus 15,000 µF at Vin = 48 V, triggered via
ON/OFF pin. Top trace: ON/OFF signal (5 V/div.).
Bottom trace: output voltage (5 V/div.). Time scale: 5
ms/div.
