the sensed location reaches 115°C. It will allow the con-
verter to turn on again when the temperature of the sensed
location falls below 110°C.
APPLICATION CONSIDERATIONS
Input System Instability: This condition can occur
because a dc/dc converter appears incrementally as a
negative resistance load. A detailed application note titled
“Input System Instability” is available on the SynQor web
site (www.synqor.com) which provides an understanding
of why this instability arises, and shows the preferred solu-
tion for correcting it.
Application Circuits:
Figure D below provides a typical
circuit diagram which is useful when using input filtering
and voltage trimming.
Figure E is a detailed look of the inter-
nal ON/OFF circuitry that is shown in
Figure A.
