Input Source Impedance
The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the power
module. Input external L-C filter is recommended to minimize input reflected ripple current. The capacitor should be equipped as close as possible
to the input terminals of the power module for lower impedance.
