Input System Instability: This condition can occur because
any dc-dc converter appears incrementally as a negative
resistanceload.Adetailedapplicationnotetitled“InputSystem
Instability”isavailableontheSynQorwebsite which provides
an understanding of why this instability arises, and shows the
preferred solution for correcting it.
Application Circuits:FigureCprovidesatypicalcircuitdiagram
which details the input filtering and voltage trimming.
Input Filtering and External Capacitance: FigureD provides
a diagram showing the internal input filter components. This filter
dramatically reduces input terminal ripple current, which otherwise
could exceed the rating of an external electrolytic input capacitor.
The recommended external input capacitance is specified in the
Input Characteristics section on the Electrical Characteristics
page.Moredetailedinformationisavailableintheapplicationnote
titled “EMICharacteristics”ontheSynQorwebsite.
