ELECTRICAL CHARACTERISTICS CURVES
For Negative Remote On/Off Logic
Figure 4: Turn-on transient at full load current) (2ms/div).
Ch3 : Vout; 2V/div; Ch2 : ON/OFF input: 2V/div.
Figure 6: Output voltage response to step-change in load
current (50%-75%-50% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF, tantalum capacitor and 0.47µF ceramic capacitor. Trace:
Vout (500mV/div). Scope measurement should be made using
a BNC cable (length shorter than 20 inches). Position the load
between 51mm to 76mm (2 inches to 3 inches) from the
module.
