5 / 14 page DS_Q48DR1R533_03152007 6 ELECTRICAL CHARACTERISTICS CURVES Figure 9: Typical full load input characteristics at room temperature Figure 10: Output voltage response to step-change in load current Iout2 (75%-50%-75% of Io, max; di/dt = 0.1A/µs) at Iout1=7.5A. Load cap: 10µF, tantalum capacitor and 1µF ceramic capacitor. Ch1=Vout2 (100mV/div), Ch2=Iout2 (7.5A/div), Ch3=Vout1 (100mV/div), Ch4=Iout1 (7.5A/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 11: Output voltage response to step-change in load current Iout1 (75%-50%-75% of Io, max; di/dt = 0.1A/µs) at Iout2=7.5A. Load cap: 10µF, tantalum capacitor and 1µF ceramic capacitor. Ch1=Vout2 (100mV/div), Ch2=Iout2 (7.5A/div), Ch3=Vout1 (100mV/div), Ch4=Iout1 (7.5A/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 12: Output voltage response to step-change in load current Iout2 and Iout1 (75%-50%-75% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF, tantalum capacitor and 1µF ceramic capacitor. Ch1=Vout2 (100mV/div), Ch2=Iout2 (7.5A/div), Ch3=Vout1 (100mV/div), Ch4=Iout1 (7.5A/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. Ch4 Ch3 Ch2 Ch1 Ch4 Ch3 Ch2 Ch1 Ch4 Ch3 Ch2 Ch1 |
