ELECTRICAL CHARACTERISTICS CURVES (CON.)

Figure 7: (For positive 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, 5V/div.

Figure 8: Output voltage response to step-change in load current

(75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF tantalum

capacitor and 1µF ceramic capacitor. Top Trace: Vout (200mV/div,

100us/div), Bottom Trace: Iout (1

/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.
