ELECTRICAL CHARACTERISTICS CURVES
Figure 1: Efficiency vs. load current for minimum, nominal, and
maximum input voltage at 25°C.
Figure 2: Power dissipation vs. load current for minimum, nominal,
and maximum input voltage at 25°C.
Figure 3: Typical full load input characteristics at room
temperature.
Figure 4: (For negative remote on/off logic) Turn-on transient at
full rated load current (5 ms/div). Vin=48V. Top Trace: Vout, 2V/div;
Bottom Trace: ON/OFF input, 2V/div.
Figure 5: (For negative remote on/off logic) Turn-on transient at
zero load current (5 ms/div). Vin=48V. Top Trace: Vout, 2V/div,
Bottom Trace: ON/OFF input, 2V/div.
Figure 6: (For positive remote on/off logic) Turn-on transient at full
rated load current (5 ms/div). Vin=48V. Top Trace: Vout, 2V/div;
Bottom Trace: ON/OFF input, 2V/div.
