ELECTRICAL CHARACTERISTICS CURVES
For Negative Remote On/Off Start up
Figure 4: Turn-on transient at full rated load current
(10 ms/div). Vin=48V. Top Trace: Vout, 1.5V/div;
Bottom Trace: ON/OFF input, 5V/div
Figure 5: Turn-on transient at zero load current
(10 ms/div). Vin=48V. Top Trace: Vout: 1.5V/div,
Bottom Trace: ON/OFF input, 5V/div
For Input Voltage Start up
Figure 6: Turn-on transient at full rated load current
(10 ms/div). Vin=48V. Top Trace: Vout, 1.5V/div;
Bottom Trace: Vin , 20V/div
Figure 7: Turn-on transient at zero load current
(10 ms/div). Vin=48V. Top Trace: Vout, 1.5V/div;
Bottom Trace: Vin, 20V/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
Figure 9: Output voltage response to step-change in
load current (75%-50%-75% of Io, max; di/dt =
1.0A/µs). Load cap: 100µF tantalum capacitor and 1µF
ceramic capacitor. Top Trace: Vout (100mV/div,
200us/div), Bottom Trace: Iout (10A/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
