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, 5.0V/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: 5.0V/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, 5.0V/div; Bottom Trace: Vin,

50V/div

Figure 7: Turn-on transient at zero load current (10 ms/div).

Vin=48V. Top Trace: Vout, 5.0V/div; Bottom Trace: Vin, 50V/div

Figure 8.1: 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 (0.15V/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

Note: for module V48SC12007NMFA, V48SC12007NMFB and

V48SC12007NRFA

Figure 8.2: Output voltage response to step-change in load

current 0A-3.2A-0A, max; di/dt =2.5A/µs). Load cap: 10µF

tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout

(0.2V/div, 200us/div), Bottom Trace: Iout (2A/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

Note: for module V48SC12007NMFP
