Note: Use a 0.1 F ceramic capacitor. Scope measurement should
be made by using a BNC socket. Position the load between
50 mm (2 in.) and 75 mm (3 in.) from the module.

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.
In addition, VI(–) is internally connected to case.

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 F electrolytic capacitor (ESR < 0.7
at
100 kHz) mounted close to the power module helps
ensure stability of the unit.
