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 components.
This filter dramatically reduces input terminal ripple current,
which otherwise could exceed the rating of an external elec-
trolytic input capacitor. The recommended external input capac-
itance is specified in the “Input Characteristics” section. More
detailed information is available in the application note titled
“EMI Characteristics” on the SynQor website.
RoHS 5/6 Compliance: SynQor products are currently 5/6
RoHS (Restriction of Hazardous Substances) compliant. The five
RoHS banned substances that our products do not contain are
Cadmium, Hexavalent Chromium, Mercury, Polybrominated
Biphenyls (PBB), and Polybrominated Diphenyl Ether (PBDE). For
additional information please e-mail info@synqor.com.
