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

Figure 5: Turn-on transient at zero load current (10 ms/div).

Vin=48V. Top Trace: Vout: 3.0V/div, Bottom Trace: ON/OFF

input, 3V/div

Figure 6: Output voltage response to step-change in load

current (50%-75%-50% of Io, max; di/dt = 0.1A/µs; Vin is 24v).

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 (length shorter than 20 inches). Position the load

between 51 mm to 76 mm (2 inches to 3 inches) from the

module
