A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 12, a 220μF electrolytic capacitor, Cin, (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. If the module is subjected to rapid on/off cycles, a 330μF input capacitor is required. Consult the factory for further application guidelines. Safety Considerations Note: Measure input reflected-ripple current with a simulated For safety-agency approval of the system in which the power source inductance (LTEST) of 12 µH.

If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module’s output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true:  The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains.  One VIN pin and one VOUT pin are to be grounded, or both the input and output pins are to be kept floating.  The input pins of the module are not operator accessible. Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or  Another SELV reliability test is conducted on the whole tantalum capacitor.
