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 (50mV/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
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 (50mV/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
