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 14, a 100 µF
electrolytic capacitor (ESR < 0.3
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.

using a BNC socket. Position the load between 50 mm and
76 mm (2 in. and 3 in.) from the module.
