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. A 33 µF electrolytic capacitor (ESR < 0.7
100 kHz) mounted close to the power module helps
ensure stability of the unit.
Note: All measurements are taken at the module terminals. When

avoid measurement errors due to socket contact resistance.
