Technical Specification
APPLICATION CONSIDERATIONS
Input System Instability: This condition can occur because
any DC/DC converter appears incrementally as a negative
resistance load. A detailed application note titled “Input
System Instability” is available on the SynQor website which
provides an understanding of why this instability arises, and
shows the preferred solution for correcting it.
Application Circuits: Figure D below provides a typical circuit
diagram which details the input filtering and voltage trimming.
Input Filtering and External Input Capacitance: 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. More detailed
information is available in the application note titled “EMI
Characteristics” on the SynQor website.
Output Filtering and External Output Capacitance:
Figure E below shows the internal output filter components. This
filter dramatically reduces output voltage ripple. However, some
minimum external output capacitance is required, as specified in
the Output Characteristics section on the Electrical Specifications
page. No damage will occur without this capacitor connected,
but peak output voltage ripple will be much higher.
