ELECTRICAL CHARACTERISTICS CURVES
For Negative Remote On/Off Logic
Figure 4: Turn-on transient at full rated load current (resistive
load) (10 ms/div). Vin=48V. Top Trace: Vout, 3.0V/div; Bottom
Trace: ON/OFF input, 3V/div
Fig ur e 5: Turn-on transient at zero load current (10 ms/d iv).
V in=48V. Top Trace: Vout: 3.0V/div, Bottom Trace: ON/OFF
input, 3V/div
Figure 6: Out put voltage response to step-change in load
current (50%-75%-50% of Io, m ax; di/dt = 0.1A/µs; Vin is 24 v).
Load cap: 10µF tantalum capacitor and 1µF ceramic capacitor.
Top Tr ace: Vout (0.5V/div, 500us/div), Bottom Trace:Iout
(5A/d iv). Scope measur ement should be made using a BNC
cable (l ength shorter than 20 inches). Po sition the load
between 51 mm to 76 mm (2 i n ches to 3 in ches) from the
module
Figure 7: Output voltage response to step-change in load
current (50%-75%-50% of Io, max; di/dt = 0.1A/µs; Vin is 48v).
Load cap: 10µF tantalum capacitor and 1µF ceramic capacitor.
Top Trace: Vout (0.5V/div, 500us/div), Bottom Trace: Iout
(5A/div). Scope measurement should be made using a BNC
cable (l ength shorter than 20 inches). Po sition the load
between 51 mm to 76 mm (2 inches to 3 inches) from the
module
