Load Current [Adc]
Fig. 5: Power dissipation vs. load current and input voltage
for converter mounted vertically with air flowing from pin 1
to pin 3 at a rate of 300 LFM (1.5 m/s) and
Ta = 25 ? C.
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 (2 V/div.). Time
scale: 2 ms/div.

Fig. 6: Power dissipation vs. load current and ambient
temperature for converter mounted vertically with
Vin = 48 V and air flowing from pin 1 to pin 3 at a rate of
200 LFM (1.0 m/s).
Fig. 8: Turn-on transient at full rated load current (resistive)
plus 10,000 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: 2 ms/div.
