JW050A, JW075A, JW100A, JW150A Power Modules:
Test Configurations

Note: Measure input reflected-ripple current with a simulated source
inductance (L

) of 12 μH. Capacitor C
S
offsets possible bat-
tery impedance. Measure current as shown above.
Figure 17. Input Reflected-Ripple Test Setup
8-513 (C).d
Note: Use a 1.0 μF ceramic capacitor and a 10 μF aluminum or tan-
talum capacitor. Scope measurement should be made using a
BNC socket. Position the load between 51 mm and 76 mm
(2 in. and 3 in.) from the module.
Figure 18. Peak-to-Peak Output Noise
Measurement Test Setup
8-749 (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.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. For the test configuration in Figure 17, a 33 μF
electrolytic capacitor (ESR < 0.7
at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit. For other highly inductive source
impedances, consult the factory for further application
guidelines.
