Over-Temperature Shutdown value. It will allow the converter to
turn on again when the temperature of the sensed location falls
by the amount of the Over-Temperature Shutdown Restart
Hysteresis value.
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 web site
(www.synqor.com) which provides an understanding of why
this instability arises, and shows the preferred solution for cor-
recting it.
Application Circuits: Figure D below provides a typical cir-
cuit diagram which details the input filtering and voltage trim-
ming.
Input Filtering and External Capacitance: Figure E
below provides a diagram showing the internal input filter com-
ponents. 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 Characterisitcs” section.
More detailed information is available in the application note
titled “EMI Characteristics” on the SynQor website.
