Test Configurations
8-203(C)
Note: Input reflected-ripple current is measured with a simulated
source impedance of 12 μH. Capacitor Cs offsets possible
battery impedance. Current is measured at the input of the
module.
Figure 10. Input Reflected-Ripple Test Setup
8-513(C)
Note: Use a 0.1 μF ceramic capacitor. Scope measurement should
be made using a BNC socket. Position the load between
50 mm and 75 mm (2 in. and 3 in.) from the module.

Measurement Test Setup
8-204(C)
Note: All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module terminals to
avoid measurement errors due to socket contact resistance.
