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
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.

socketing, place Kelvin connections at module terminals to
avoid measurement errors due to socket contact resistance.
