For Negative Remote On/Off Logic
Figure 4: Turn-on transient at full rated load current (resistive
load) (5 ms/div). Vin=48V. Top Trace: Vout, 2.0V/div; Bottom
Trace: ON/OFF input,2V/div
Figure 5: Turn-on transient at zero load current (5 ms/div).
Vin=48V. Top Trace: Vout: 2.0V/div, Bottom Trace: ON/OFF
input, 2V/div

Figure 8: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (100mV/div, 200us/div
)
, Bottom Trace: Iout (5A/div).
Scope measurement should be made using a BNC cable
(length shorter than 20 inches). Position the load between 51
mm to 76 mm (2 inches to 3 inches) from the module
